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] package.name.pkg

   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
Usage: pkgutil [OPTIONS] [COMMANDS] ...

Options:
  --help                 Show this usage guide
  --verbose, -v          Show contextual information and format for easy reading
  --force, -f            Perform all operations without asking for confirmation
  --volume PATH          Perform all operations on the specified volume
  --edit-pkg PKGID       Adjust properties of package PKGID using --learn PATH
  --only-files           List only files (not directories) in --files listing
  --only-dirs            List only directories (not files) in --files listing
  --regexp               Try all PKGID arguments as regular expressions

Receipt Database Commands:
  --pkgs, --packages     List all currently installed package IDs on --volume
