What is a shell?

A shell provides the user with various functions of the system using certain commands; that is, it allows the system to be controlled. By default, most Linux distributions use the bash shell. Its function is to recognize and read the input commands, and then call the necessary programs.

About a shell script

A script is a sequence of commands written to a special file, and the shell reads these commands from the file and interprets them. To create such a shell, you need a special program: a text editor. Fortunately, there are a lot of such programs, so you can use any of them to create a shell script.

The structure of a shell script

Consider the first 3 lines of a script:

  • The first line usually starts with #! /bin/bash - this suggests that you want to use the bash shell.
  • Next up is /bin/bash. This second line is necessary to create a cleanup command, which deletes the commands that were there before. The output from the console or terminal window in which the command was executed also occurs.
  • The third line is for entering the required message using a simple echo command. Sometimes you can use quotation marks; this is especially convenient and useful for complex tasks in volume programming.
