With the Bash shell, you can navigate through directories, manipulate files and directories, and perform various system tasks. It supports a wide range of commands, such as “ls” to list the contents of a directory, “cd” to change directories, and “cp” to copy files.
In addition to executing commands, the Bash shell also supports scripting. A shell script is a file containing a series of commands that can be executed sequentially. This allows you to automate repetitive tasks or create complex workflows. Shell scripts are written in Bash scripting language and can be executed like any other program.
The command line interface provides a direct and efficient way to interact with your computer. It allows you to execute commands quickly, without the need to navigate through menus or click on icons. The command line interface is also highly customizable, allowing you to configure your environment to suit your needs.
Taking Linux training will help you learn how to use the Bash shell and command line interface effectively. You will gain a deeper understanding of Unix-like systems, improve your computer programming skills, and develop best practices for working with the command line.
