extract plugin

This plugin defines a function called extract that extracts the archive file
you pass it, and it supports a wide variety of archive filetypes.

This way you don't have to know what specific command extracts a file, you just
do extract <filename> and the function takes care of the rest.

To use it, add extract to the plugins array in your zshrc file:

plugins=(... extract)
