A generalization of previous patterns and tips.

Motivation:

Every script must have certain functionality like a help option or an edit option. How incorporate those functionalities without add complexity and extra work to the script?

Solution:

Create a script that hold the functionality needed to add extra options to new scripts. Then, in every new script call that script for added functionalities.

Create a file named paramPattern.sh containing:


        scriptPath=`type $1 | awk '{ print $3 }' `

        case $2 in

        -edit)

        ${EDITOR:-vi} $scriptPath

        exit 1

        ;;

        -help)

        sed -n '/^##/s/^## //p' $scriptPath

        exit 2

        ;;

        esac

        exit 0

In existing or new scripts insert:


        paramPattern $0 $1 ||

        exit 1

        ...
