What is PowerShell?
Bash (Bourne Again Shell) is a Unix shell and command language, widely used as the default shell on Linux and macOS. It is a powerful tool for system administration, scripting, and automation.
Key Features of Bash
Command-Line Interface (CLI):
Bash provides a text-based interface where users can type commands to interact with the operating system.
Scripting Language:
Bash supports writing scripts, which are collections of commands saved in a file. These scripts can automate repetitive tasks.
Compatibility:
Bash is backward-compatible with the Bourne shell (sh), and many commands are also compatible with other Unix shells.
Pipelines:
Bash supports piping, where the output of one command can be passed as input to another command using the pipe (|) operator.
Variables:
Bash supports variables, which can store data such as strings and numbers, and can be used in scripts to create dynamic content.
