wiiki - ParamPattern

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
