ParamPattern

Last edit October 3, 2003

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
  ...
