macOS bash script to close all non-essential apps – like “Close all browser tabs” but for apps

killapps.sh

#!/bin/sh

# Example: kill all non-development apps:
#   . killapps.sh dev
# Example: kill all non-office apps in a soft way:
#   . killapps.sh office soft

# Strip leading and trailing white space (new line inclusive).
