# DevOps 102: Linux Basic Commands

Linux is a popular choice for DevOps professionals because it is a stable, flexible, and open-source operating system that can be easily customized to fit the needs of any organization. One thing that makes Linux so powerful is its command-line interface (CLI), which allows for automation and scripting, making it well-suited for DevOps workflows, which aim to automate the software development and deployment process.

It also allows users to perform various tasks by typing commands into the terminal. In this blog of the DevOps series, we'll go over some basic Linux commands that every Linux user should know.

1. `ls`: This command is used to list the files and directories in a directory. By default, `ls` will show the contents of the current directory.
    
    ```bash
    ls
    ```
    
2. `cd`: This command is used to change the current working directory. For example, `cd /home` will change the current directory to `/home`, and `cd` on its own will take you to your home directory.
    
    ```bash
    cd folderName
    ```
    
3. `pwd`: This command is used to display the path of the current directory that you are currently in. When you run the `pwd` command, it will display the absolute path of the current directory, which is the full path from the root directory (`/`) to the current directory. For example, if you are currently in the `/home/user/documents` directory, running the `pwd` command will display `/home/user/documents`.
    
    ```bash
    pwd
    ```
    
4. `mkdir`: This command is used to create a new directory. For example, `mkdir mynewdir` will create a new directory called `mynewdir` in the current directory.
    
    ```bash
    mkdir newFolderName
    ```
    
5. `touch`: This command is used to create a new empty file. For example, `touch mynewfile.txt` will create a new file called `mynewfile.txt` in the current directory.
    
    ```bash
    touch newFileName
    ```
