Shell Programming Language
Bash is a Unix shell and command language. It is the default shell on most Linux distributions and macOS.
#What is Shell?
Shell Programming Language, commonly referred to as Shell Scripting, is a scripting language used for automating tasks on Unix/Linux systems. Shell scripts are used to execute multiple commands sequentially or simultaneously to automate complex tasks. Shell scripting is considered to be one of the essential skills for system administration, DevOps, and IT professionals who work on Unix/Linux systems.
#Shell Key Features
