Play rar archives and directories with mplayer/gmplayer

gmplayer.sh

#!/bin/bash
# gmplayer.sh - Builds and play a playlist based on the command line arguments
#
# * Command line arguments may include rar files or directory names.
#
# * Other mplayer options are preserved unless there is a file or directory
#   matching the literal value.
#
# * To overcome this, command line parameters are not parsed anymore after "--"
#   is encountered, and ignored after parameters listed in SKIP_PARAM below.
#
# * Symbolic links to directories are ignored to avoid recursion.
#
# INSTALLATION: Copy this script in ~/bin/gmplayer or /usr/local/bin/gmplayer
