There are a lot of different tools that you can use to manage your infrastructure, but one of the most popular is Ansible. One reason why Ansible is so popular is because it uses YAML, which is a human-readable data format. This means that you don’t need to be a programmer to use Ansible.

If you’re new to Ansible, or YAML in general, then you might find yourself looking for a cheat sheet. In this blog post, we’ll provide you with an Ansible Yaml cheat sheet that will help you get started with using Ansible.

If you’re looking for a quick and easy way to get started with Ansible, look no further than this Ansible Yaml Cheat Sheet. This one-page guide provides all of the most important information you need to get up and running with Ansible, including a description of all of the most important concepts and keywords. So whether you’re just getting started or you’re already an Ansible expert, this cheat sheet is a handy reference to have on hand.

How to write your first Ansible playbook | Write Simple Ansible Playbook | Learn Ansible Basics

Ansible Playbook Examples

Ansible is a powerful configuration management tool that can be used to manage both small and large infrastructure deployments. In this post, we’ll take a look at some Ansible playbook examples to illustrate how easy it is to get started with this tool. First, let’s take a look at a simple example that installs the Apache web server on a target host.

This playbook uses the ansible-playbook command to run the tasks defined in the apache.yml file: – hosts: all become: true

roles: – { role: apache } In this case, we’re using the ansible-playbook command to install the Apache web server on all hosts in our inventory.

We’re also using the become directive to gain root privileges on our target hosts so that we can install software packages. Next, let’s take a look at another simple playbook that configures an Nginx web server. This time, we’ll use the include directive to include tasks from another file (nginx-tasks.yml) so that our playbook is more modular and easier to read:

– hosts: all become: true roles:

– { role: nginx } tasks: # These will execute after role has been applied # You can put anything here really… even conditionals!

How Do You Use Ansible Reference Guide?

Ansible is a powerful configuration management system used to set up, manage, and deploy applications and services. The Ansible reference guide provides all the information you need to use Ansible effectively. To get started using Ansible, you first need to install it on your control node.

After that, you can create playbooks containing tasks that will be executed on your managed nodes. Playbooks are written in YAML, which makes them easy to read and understand. Once you have created a playbook, you can run it using the ansible-playbook command.

This will execute all of the tasks in the playbook on the specified nodes. You can also use the ansible-playbook command to run individual tasks from a playbook. The Ansible reference guide contains all of the information you need to use Ansible effectively.

If you have any questions about how to use Ansible, feel free to ask in the comments section below or reach out to the Ansible community for help.

How Do I Pass Ansible Username And Password?

If you’re looking to pass Ansible username and password variables, there are a few ways to do it. The most common is to use the ‘ansible_ssh_user’ and ‘ansible_ssh_pass’ variables in your playbooks. However, these can be easily passed as extra vars on the command line:

$ ansible-playbook -u myuser -k myplaybook.yml Alternatively, you can create an inventory file with your credentials included: [all]

host1 ansible_ssh_user=myuser ansible_ssh_pass=mypass

How Do I Check My Ping Pong in Ansible?

Ansible is a powerful configuration management and orchestration tool that can be used to manage complex deployments. One of the great features of Ansible is its ability to check the status of remote hosts and services. In this blog post, we’ll show you how to use Ansible to check your ping pong server’s status.

First, let’s create an ansible playbook called “check-pingpong-status.yml” in our project’s root directory: — – name: Check Ping Pong Status

hosts: all gather_facts: no tasks:

– name: Check if Ping Pong Server is running command: ps aux | grep -v grep | grep ‘pingpong’ register: pingpong_status

changed_when: false

What are the Basic Terminologies Used in Ansible?

Ansible is a powerful open source tool that can help you automate various tasks on your servers. In this blog post, we will take a look at some of the basic terminologies used in Ansible so that you can better understand how it works. The first term we will look at is “playbook”.

A playbook is a file that contains a list of instructions for Ansible to follow. These instructions can be anything from installing software to configuring services. Playbooks are written in YAML, which is a human-readable data format.

Next, we have “roles”. Roles are like mini-playbooks that can be used to group together related tasks. For example, you might have a role for installing Apache and another role for setting up a database server.

This makes it easy to reuse parts of your playbook across different projects. Finally, we have “inventory”. Inventory is simply a list of hosts that Ansible will run playbooks on.

This list can be static or dynamic, and it can be stored in multiple formats (including INI and JSON).

Conclusion

Ansible is a powerful configuration management tool that lets you control large numbers of servers in an automated way. This Ansible Yaml Cheat Sheet will help you learn the basics of working with Ansible so that you can get started managing your infrastructure. The cheat sheet covers the basic syntax of Ansible’s yaml files, as well as some of the most common tasks that you can perform with Ansible.

After reading this cheat sheet, you should be able to write simple playbooks and understand how ansible works.

A bind shell is a form of shellcode that opens up a new listening port on the target machine and executes commands from there. This type of shellcode is usually used in order to bypass firewalls since it uses an existing connection that is already allowed instead of creating a new one. Bind shells can be used in order to gain control of a machine by an attacker and are often used in conjunction with other exploits in order to gain access to a system.

In this article, we will provide a bind shell cheat sheet that can be used by penetration testers and red teams during their engagements.

A bind shell is a type of shellcode that gives an attacker remote access to a machine by binding a shell to a port on the machine. This allows the attacker to connect to the machine and issue commands as if they were logged in locally. Bind shells are often used by attackers to gain initial access to a machine and then pivot to other machines on the network.

There are many ways to create bind shells, but they all involve creating a socket and binding it to a port on the machine. The attacker then connects to this port and issues commands, which are executed by the shellcode on the target machine. One common way to create bind shells is with Netcat.

Netcat is a utility that can be used for networking tasks like creating sockets and transferring data over them. It can also be used for creating bind shells. To do this, the attacker first starts Netcat on their own machine, listening on a specific port:

nc -lvp 4444 Then, they use Netcat on the target machine to connect back to their own machine and send commands:

What is Bind Shell in Metasploit?

A bind shell is a type of shell in which the victim machine opens up a server that allows the attacker to connect to it and run commands as if they were logged into the victim machine. The attacker can then use this access to do anything they want on the victim machine, such as installing malware, stealing sensitive data, or even taking over the entire machine. One of the most popular ways to get a bind shell is by using Metasploit, which is a tool that allows attackers to exploit vulnerabilities in systems.

Once Metasploit is installed on a system, an attacker can use it to create a malicious file that when opened by the victim will give the attacker control of their machine. This file can be sent to the victim in any number of ways, such as through email, social media, or even physical means such as USB drives. Once the victim opens this file, the attacker will have full control over their system and can do anything they want with it.

This makes bind shells extremely dangerous and something that all users should be aware of. If you ever receive a suspicious file from someone you don’t know, make sure not to open it!

What is the Difference between a Bind Shell And a Reverse Shell?

In computing, a shell is a user interface for access to an operating system’s services. In general terms, a shell is a program that takes commands from the keyboard and gives them to the operating system to perform. Shells are used on nearly every operating system in existence and are mostly unique to each one.

A bind shell is created on the victim machine, allowing an attacker who has compromised the machine to connect back to it using a network connection. The attacker then has full control over the machine as if they were sitting at its console. Bind shells can be setup so that they listen on any port, making them very difficult to detect.

A reverse shell is also created on the victim machine, but instead of binding to a port on the machine, it connects back out to another server controlled by the attacker. Once connected, the attacker again has full control over the machine as if they were sitting at its console. Reverse shells can be tricky to get right due partly because many firewalls block incoming connections unless they are expected (like SSH or FTP).

What is Netcat Bind Shell?

A bind shell is a type of shell in which the primary purpose is to listen for incoming connections from clients. It is typically used to execute commands on remote hosts and can be configured to work with a variety of different protocols. Netcat is a popular tool for creating bind shells.

When configuring a bind shell, the attacker must specify an IP address and port number that the shell will listen on. The attacker must also specify the protocol that will be used (e.g., TCP or UDP). Once the bind shell is configured, the attacker can start it by running the netcat command with the appropriate options.

Clients can then connect to the IP address and port specified by the attacker and send commands that will be executed by the bind shell. The output of these commands will be sent back to the client. Bind shells can be used to perform a variety of tasks, such as downloading and executing files, accessing sensitive information, or adding new users.

While bind shells are very useful for attackers, they can also pose a serious security risk. If not properly configured,bind shells may allow unauthorized access to systems or networks.

Does Php Reverse Shell Work on Windows?

Yes, PHP reverse shell works on Windows. Here’s how it works: First, the attacker creates a PHP script that will act as the reverse shell.

This script will connect back to the attacker’s machine and give them a command prompt. The attacker then uploads this script to the target machine, usually via a web server or FTP server. Once the script is on the target machine, the attacker can execute it by visiting its URL in a web browser.

This will cause the PHP code to run and connect back to the attacker’s machine. Once connected, the attacker will have full control of the target machine and can issue commands as if they were sitting at its keyboard.

Bash Bind Shell

A bind shell is a type of shellcode that opens up a new instance of a shell and binds it to a specific port. This allows an attacker to connect to the host machine by connecting to the specified port. Bind shells are often used by attackers after gaining access to a system in order to gain further access.

There are two main types of bind shells: Windows and Unix. Windows bind shells typically use the port 4444, while Unix bind shells usually use ports 2048-65535. The Windows version is usually generated using Metasploit, while many different methods can be used for creating Unix bind shells.

Once an attacker has created a bind shell, he or she can then connect to it using any number of tools, such as netcat, telnet, or even ssh. Once connected, the attacker will have full control over the victim machine and can issue commands as if they were logged in locally. Bind shells can be very dangerous because they allow attackers full control over victim machines.

They should therefore be avoided unless absolutely necessary.

Conclusion

A bind shell is a type of shellcode that opens up a new instance of a shell and binds it to a listening port. This gives an attacker full control over the victim machine, as they can issue commands and interact with the system just like a legitimate user. There are many ways to generate bind shellcode, but one of the most popular methods is to use Metasploit’s msfvenom tool.

This tool can be used to create both Windows and Linux bind shells, making it a versatile option for attackers. Once generated, the bind shellcode can be embedded in an exploit or delivered via social engineering techniques. Once executed, the attacker will have full control over the victim machine and could even install additional malware or exfiltrate sensitive data.

Basic BGP neighbor configuration

How Do Birds Use Bgp?

BGP, or Border Gateway Protocol, is a routing protocol that helps direct traffic on the internet. It’s what allows your computer to know how to get from Point A to Point B when you type in a web address. Just like your car needs gas to run, BGP directs packets of data between autonomous systems (ASes) on the internet.

Birds use BGP for two main reasons: first, to help direct traffic on the internet; and second, because it’s more efficient than other routing protocols. When you type in a web address, your computer sends out a request for that website. That request is then routed through the internet using BGP.

The route is determined by looking at the AS path – which ASes the request will go through to get to its destination. By looking at the AS path, BGP can determine the best route for that request. BGP is more efficient than other routing protocols because it uses less processing power and memory.

It’s also scalable – meaning it can handle more traffic as the internet grows. This makes it an ideal choice for directing traffic on the internet – which is why birds use it!

What is Bird in Networking?

BIRD is a network daemon that runs on most Unix-like systems and implements the Border Gateway Protocol (BGP) and other routing protocols. BIRD is open source software, released under the GNU General Public License. The name “BIRD” is an acronym for “BIRD Internet Routing Daemon”.

The logo depicts a common bird with its wings spread wide, representing the free software nature of the project as well as its aim to support all kinds of network traffic. Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. An AS can be either a standalone system such as a company network or it could be part of another AS.

In order to allow two or more ASes to communicate with each other, they must agree on some set of rules, called an exterior gateway protocol (EGP). The most commonly used EGP today is Border Gateway Protocol version 4 (BGP-4), defined in RFC 4271. It should be noted that while BGP-4 is often referred to simply as “BGP”, there have been several earlier versions of the protocol; however, these are no longer in widespread use.

In general terms, BGP works by having each AS announce which networks it can reach, along with some attribute indicating how desirable those networks are as routes. Other ASes then use this information when making their own decisions about where to send traffic destined for those announced networks.

What is Bgp Protocol?

BGP (Border Gateway Protocol) is a routing protocol for the Internet. It is the successor to the Interior Gateway Protocol (IGP) RIP (Routing Information Protocol) and OSPF (Open Shortest Path First). BGP makes decisions on which route to take based on policies set by network administrators and propagates those routes throughout the network.

BGP uses TCP as its transport protocol and can be used to exchange routing information between different autonomous systems (ASes). The main purpose of BGP is to ensure that data packets are routed efficiently and correctly across the Internet. BGP accomplishes this by maintaining a table of IP networks and their associated ASes.

When a BGP speaker receives an update about a new route, it looks up the ASN in its table to see if it should accept the update. If so, it updates its own routing table and propagates the new route to all of its neighbors. BGP is considered a path vector protocol because it makes routing decisions based on vectors, or paths, rather than metrics like cost or delay.

This means that BGP does not simply choose the shortest or fastest path between two points; instead, it chooses a path based on factors such as reliability, security, policy compliance, etc. One of the most important features of BGP is its ability to support multihoming, which means connecting an AS to multiple ISPs in order to increase redundancy and improve performance. In the event that one ISP goes down, traffic can be rerouted through another ISP without interrupting service.

Another key feature of BGP is policy-based routing, which allows administrators to control how traffic flows through their network using various policies. For example, an administrator might want to prefer certain routes over others based on criteria such as latency or jitter.

Is Bgp Open Source?

BGP is a routing protocol that is used to exchange routing and reachability information among autonomous systems on the Internet. BGP is the only routing protocol that is capable of supporting this type of environment. BGP uses a path vector algorithm to select the best path for forwarding traffic.

BGP makes decisions based on policies set by network administrators. This allows for more granular control over how traffic is routed. BGP is not an open source protocol.

It is a proprietary protocol developed by Cisco Systems. However, there are Open Source implementations of BGP such as Quagga and FRRouting.

Bird Bgp Example

In computer networking, Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol. BGP neighbors, called peers, are established by manual configuration between routers to create a TCP session on port 179.

BGP uses the concept of Autonomous System Numbers (ASNs) in order to maintain its routing table. ASNs are unique numbers that identify an autonomous system such as an ISP or enterprise network. BGP runs over Transmission Control Protocol (TCP), which ensures that all data packets are delivered in sequence and without error.

The main purpose of BGP is to ensure that packets are routed along the best path possible, based on network conditions at the time of packet transmission. To do this, BGP makes use of several attributes including: Weight: A router’s locally assigned importance; used by some Cisco IOS versions when choosing among multiple EBGP routes with equal preference values supplied by different neighbors

Local Preference: Affects route selection for all types of traffic; can be set manually or automatically using policy-based routing Origin Code: Indicates where the route originated; I=IGP (Interior Gateway Protocol), E=EGP (Exterior Gateway Protocol), ?=incomplete

AS Path Length: Used as tiebreaker when multiple paths exist to the same destination with equal weight or local preference values; shorter paths are preferred MED (Multi-Exit Discriminator): Used as tiebreaker when multiple paths exist from one AS to another AS; lower MED values are preferred

Conclusion

This blog post provides a cheat sheet for the Border Gateway Protocol (BGP), which is a routing protocol used to exchange information between different networks. The cheat sheet covers the basics of BGP, including its history, how it works, and common commands. It also includes a list of resources for further reading.

How Do I Use Jql in Jira?

JQL, or Jira Query Language, is a powerful tool that allows you to search and filter issues in Jira. You can use JQL to find issues based on certain criteria, such as the status of an issue, the assignee of an issue, or the date an issue was created. To use JQL, simply type your query into the search bar in Jira.

For example, if you want to find all issues that are open and assigned to you, you would type: “assignee = currentUser() AND status = open”. You can also use wildcards in your queries to find multiple issues at once. For example, if you want to find all issues with the word “bug” in their summary, you would type: “summary ~ bug”.

JQL is a very powerful tool that can help you get the most out of Jira. If you have any questions about how to use JQL, please don’t hesitate to reach out to our support team.

How Can I Learn Jql?

JQL, or Jira Query Language, is a query language designed specifically for use with the popular issue tracking software Jira. While it is possible to learn some basics of JQL without any prior knowledge of programming or database query languages, to really get the most out of it and be able to write complex queries, some knowledge of programming concepts is necessary. In this article we’ll take a look at what you need to know in order to start learning JQL.

The first thing to understand about JQL is that it is not simply a database query language like SQL. Rather, it was designed specifically for the purpose of querying data within Jira issue trackers. As such, it has a number of features and syntaxes that are specific to Jira and may not be familiar to those who are used to working with other database query languages.

That said, there are still many similarities between JQL and other query languages, so those with some experience in writing queries should have no trouble picking up the basics of JQL. One important thing to note about JQL is that its main focus is on issues rather than projects. In other words, when you write a JQL query you are primarily concerned with retrieving information about specific issues rather than project-level data.

This can be a bit confusing at first if you’re used to thinking about projects as being the primary entity in an issue tracker but it does make sense once you start using JQL and seeing how powerful it can be for finding specific issues. To get started writing your ownJQL queries, the best place to begin is by taking advantage of the built-in documentation provided by Atlassian (the company behindJira). This documentation includes an extensive list of all the available functions and operators that can be used inJQL queries along with examples of how they can be used.

Once you’ve familiarized yourself with the available functions and operators, you’ll be readyto start writing your own queries!

Can You Do Math With Jql?

Yes, you can do math with JQL! You can use the +, -, *, and / operators to perform mathematical operations on numeric fields in your JQL queries. For example, if you want to find all issues that are assigned to you and have a priority of 4 or higher, you could use the following query:

assignee = currentUser() AND priority >= 4 You can also use parentheses to group together multiple mathematical operations. For example, if you want to find all issues that are assigned to you and have a priority of 4 or higher, but only return those with a status of “Open” or “In Progress”, you could use the following query:

Is Jql Same As Sql?

JQL and SQL are two very different things. JQL is a query language specific to Jira, while SQL is a more general purpose database query language. While they share some common features, they are not the same thing.

Jira Basic Search – JQL 101

Jira Jql Examples

JQL, or Jira Query Language, is a powerful tool that lets you search and filter issues in Jira. With JQL, you can find the right issues faster and make better decisions about what to work on next. There are many different ways to use JQL.

In this blog post, we’ll share some of our favorite JQL examples so you can get the most out of your Jira queries. 1. Find all issues assigned to a particular person If you want to find all of the issues that are assigned to a specific person, you can use this JQL query:

assignee = “User Name” 2. Find all open bugs To find all open bugs in your project, you can use this simple query:

status = “Open” AND issuetype = “Bug” 3. Find all high priority issues If you want to find all of the high priority issues in your project, you can use this query:

priority = High 4. Find all blockers A blocker is an issue that is preventing other work from being done.

To find all blockers in your project, you can use thisquery: status = “Open” AND resolution = Unresolved AND priority >= Blocker 5. Find recently updated issues

It can be helpful to see which issues have been updated recently so you know where people are working on currently. To do this,you can use this query:

If you’re an Atlassian user, then you know how helpful JQL can be. But what if you’re not an expert? This cheat sheet will help you get started with JQL and find the information you need faster.

JQL, or the Java Query Language, is a powerful tool for querying Atlassian products. You can use it to find issues, filter search results, and even create custom reports. To use JQL, simply type your query into the search bar in any Atlassian product.

For example, if you want to find all of the tickets that are assigned to you, you would type: assignee = currentUser() You can also use JQL to filter search results. For example, if you only want to see tickets that are high priority, you would type: priority = High

And finally, you can use JQL to create custom reports. Reports show up in the “Reports” section of each product and allow you to track progress on specific projects or issues over time. To create a report, click on the “Create Report” button in the Reports section and select “Custom Report.”

Then choose the fields that you want to include in your report and specify your filters. That’s it! Your report will now be available for anyone to view.

What is $@ in Bash?

In bash, $@ is a special variable that represents all of the positional parameters (arguments) in an array. This means that when you use $@ as an argument to a command, each element in the array will be expanded into a separate word. For example, if you have a script that takes two arguments and prints them out, you could use $@ like this:

./myscript.sh one two This would print “one” and “two” on separate lines.

What are Basic Bash Commands?

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. First released in 1989, it has been distributed widely as the default login shell for most Linux distributions and Apple’s macOS Sierra and earlier versions. A version is also available for Windows 10.

Bash is a powerful programming language that provides many tools for managing files and directories, manipulating text, running programs, and much more. In this article, we’ll give you a brief introduction to some of the most common bash commands. The ls Command

ls is one of the most commonly used bash commands. It’s used to list the contents of a directory. For example, if you want to see what files are in your current directory, you can use ls like this:

$ ls This will print a list of all files (and subdirectories) in your current directory. By default, ls will list files in alphabetical order.

However, there are many options you can use to customize the output. For example, if you want to list files in reverse alphabetical order, you can use the -r option: $ ls -r

What is $1 And $2 in Bash?

$1 and $2 are special variables in bash that refer to the first and second positional parameters passed to a function, script, or program. Positional parameters are a series of special variables used by many programming languages, including bash, that hold the values of the arguments supplied to a program or function. The first argument is typically stored in $1 , the second argument in $2 , and so on.

In bash, $0 always refers to the name of the currently executing script or program. However, $1 and $2 will only be populated if they are actually provided as arguments when calling a script or program. For example:

./script.sh arg1 arg2 # sets $1 = “arg1” and $2 = “arg2” ./script.sh # sets only $0 = “./script.sh”, since no args were provided If you attempt to reference a positional parameter that wasn’t set (e.g., trying to print $3 when only two arguments were provided), you’ll simply get an empty string outputted:

How are R Commands Written?

There is no one answer to this question as it depends on the particular r command you are wanting to write. However, in general, most r commands are written in a similar fashion. They typically start with a keyword, such as “function” or “for”, followed by a set of parentheses.

Inside the parentheses, you will usually find one or more arguments that need to be supplied in order for the command to work correctly. For example, the following is a very simple r command that would create a new function: function(x){

return(x*2) } In this case, the keyword is “function” and the only argument inside the parentheses is “x”.

The code inside the curly braces defines what this function will actually do when it is called – in this case, it will simply take whatever value is supplied for x and multiply it by 2. Of course, not all r commands are this simple – some can be quite long and complex. However, understanding how they are generally structured will help you better understand how to use them.

What is the Base of R?

R is a statistical programming language that was developed in the early 1990s. The base of R is an interpreted computer language which allows for easy access to statistical techniques and data analysis. In addition, the base of R provides a wide range of graphical facilities.

How Do You Learn R?

There is no one answer to this question since everyone learns differently and what works for one person might not work for another. However, there are some general tips that can help when learning R. First, it is important to find good resources such as books, websites, and online courses that cover the basics of the language. Once you have a basic understanding of the syntax and how to write code, it is important to practice by writing your own code and trying out different commands on real data.

It can also be helpful to join an online community or forum where you can ask questions and get help from other R users. Finally, it is also beneficial to attend conferences or workshops where you can learn from more experienced users and see how others are using R in their work.

What Means Cheat Sheets?

A cheat sheet is a reference guide that provides concise, essential information on a particular topic. Cheat sheets are typically used as quick, last-minute references by students or professionals who are already familiar with the main concepts of a subject but need to remind themselves of specific details. There is no single definition of what constitutes a cheat sheet, but they are generally considered to be concise and easy-to-use references that provide essential information on a particular topic.

Cheat sheets can take many different forms, from simple lists of facts or equations to more complex and detailed guides. Regardless of their format, all cheat sheets share the same goal: to provide quick and easy access to vital information. While there is no shortage of online resources for finding cheat sheets on virtually any topic, some students and professionals prefer to create their own.

Creating a custom cheat sheet is often seen as an opportunity to consolidate and organize important information in a way that best suits one’s individual needs. For others, the act of creating a cheat sheet can itself be helpful in mastering the material covered therein.

Conclusion

R is a programming language that is widely used by statisticians and data scientists. The R language is designed to be simple and easy to use, and this cheat sheet will help you get started with some of the most basic commands. The first thing you need to do when using R is to set up your working directory.

This is the folder on your computer where all your R files will be stored. To do this, open RStudio and go to File > New Project. Choose where you want to save your project, give it a name, and click Create Project.

Once your project is set up, you can start creating R scripts. A script is simply a text file containing a series of R commands. To create a new script, go to File > New File > R Script.

This will open a new window where you can type in your commands. To run a command, simply type it into the console and press Enter. For example, if we wanted to find out what version of R we are using, we would type:

> version Which would output: _

platform x86_64-w64-mingw32 arch x86_64 os mingw32

system x86_64, mingw32 status major 3 minor 5.1 year 2018 month 07 day 02 svn rev 75600 language English version 3.5 .1RC (2018 – 07 – 02 r75600)
