argtest

Tests if an argument is supplied

Usage

argtest [argument] [search arguments]

If argtest finds argument within search arguments it will halt with an exit code of 0. If either to few arguments are supplied (<2) or argtest doesn't find argument, it will halt with an exit code of 1.

Example (see test.sh):

#!/bin/sh

if ./argtest foo $@; then
  echo foo is in args
else
  echo foo is not in args
fi

Output:

$ sh test.sh bar
foo is not in args

$ sh test.sh bar foo
foo is in args
