macOS - Dealing with Packages (script)

This is a simple bash script to shorten the commands I frequently use to deal with installed packages (.pkg).

  macos [~] $ pkg

   Usage: pkg [option]

   Options: -l  list all installed packages
            -i  show package info
            -a  list package files and directories
            -f  list package files only
            -d  list package directories only
            -r  remove package files
            -o  open receipts location

The script makes use of the pkgutil to perform the tasks above. Here is pkgutil's help:

  macos [~] $ pkgutil --help
