Writing Unix script to accept arguments

Hi,

This may be answered elsewhere but I wasn't entirely sure of the wording I should use to search so here we go with an attempt:

I wish to make a script that will allow commands to be passed to it such as:

<command> -oOPTIONS -aANOTHER -pRINT

etc

However I don't really know the syntax of what to do ir how to accept them with in the code.

Like for example:

If I want it do run a certain command if -o equals "Fred".

If anyone has any help or "how to's" it would be most apprieciated.

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com- mand. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
