Linux Shell Script Examples of the BASH ''for'' Loop - Lifewire

Aug 27, 2019· A key part of any programming and scripting language is the ability to run the same piece of code again and again. BASH offers several ways to repeat code — a process also known as looping.A for loop repeats a certain section of the code over and over. They''re useful so that a series of commands can keep running until a particular condition is met, after which they''ll stop.
