Более сжатый способ

script.sh

#!/bin/bash

while [[ "$#" > 0 ]]; do case $1 in
  -d|--deploy) deploy="$2"; shift;;
  -u|--uglify) uglify=1;;
  *) echo "Unknown parameter passed: $1"; exit 1;;
esac; shift; done

echo "Should deploy? $deploy"
echo "Should uglify? $uglify"

Использование:

./script.sh -d dev -u

# OR:

./script.sh --deploy dev --uglify
