Shell Functions

Shell functions are reusable blocks of code within a command-line environment, like a script or terminal session. They allow users to group commands together under a name, making complex tasks easier to execute repeatedly. Instead of typing the same commands multiple times, you define a function once and call it by name whenever needed. This improves efficiency, organization, and readability of scripts or command sequences. Think of shell functions as personalized shortcuts that automate specific sets of actions, streamlining workflows in the command-line interface.
