The 'exit' command allows you to stop a running shell script at any point and to return a "status" value back to whomever called the shell script. This is a very common practice with shell scripts; sometimes you want to stop the script before it gets to the end of the shell script (for various logic reasons). The 'exit' command also allows you to give a status that any other calling process can use to determine if the shell script ended successfully or not.

A shell function will do nothing unless it is explicitly called by other code, typically in a shell script. A shell script is a runnable, executable process, which can call other shell scripts and/or functions.

Consider a shell function equivalent to a program subroutine - they operate the same way.
The C shell is a unix shell created by Bill Joy as a graduate student at University of California, Berkeley in the late 1970s. The C shell runs in a text window and processes user commands. The C shell can also read commands from a script. It supports piping, here documents, command substitution, variables, control structures for condition-testing and looping and filename wildcarding.
