shflags

Command-line flags module for Unix shell scripts

shFlags is a port of the Google gflags library for Unix shell. The code is written in a way to be as portable as possible to work across a wide array of Unix variants. shFlags is simply a library that you include into an existing shell script that gives you some additional functions that can be called. The power behind those functions though is somewhat amazing though, and you will hopefully be amazed with the simplicity with which you can handle command-line arguments in shell.
