jdtt - accept command line arguments for 'yum', 'apt', or 'port' and just do the thing based on the platform

jdtt

#!/usr/bin/env bash
##
##  Accept arguments from popular package management tools (except Homebrew)
##  and just do the right thing, based on the platform.
##
##  Created out of frustration at typing `yum` on Macs and `port` on Linux
##  boxes, and `apt` on RHEL/CentOS boxes all too often.

Symlink as yum, apt, and port and relax. It'll do the thing.

To-do

• rpm -qa, dpkg -l, and port echo installed - list installed packages
• rpm -ql, dpkg -L, and port list - list specific package's contents
• rpm -qf, dpkg -S, and port provides - which package owns a specific file?
• port deps port rdepends, apt-cache rdepends, and whatever the rpm version is - all those ones I can never remember that answer the questions "which packages does this package require?" and "which packages require this package as a dependency?"
