keypress - ir remote key emulation on command line

[RaenonD]

This wiki page lists most of the ir codes available for the popcorn hour, so that you can control the device from telnet. This is all well and good, but somehow, I don't remember hexidecimal keycodes all that well.

So, I wrote a script to remember it for me, and saved it as /share/bin/keypress

Code:

#!/bin/sh
# Script to emulate keypresses of Popcorn Hour (tm) IR remote control from command line using human-readable arguments

ERROR=0
ARGV="$@"
if [ "x$ARGV" = "x" ] ; then
    ARGS="help"
fi

Upload the file to /share/bin, then "chmod +x /share/bin/keypress" to make it executable, and suddenly, you can type out your commands in clear, human-readable text (with only a small amount of abbreviation).

Code:

# keypress
usage: /share/bin/keypress <command>
Acceptable commands should include all keys
available on the Popcorn Hour (tm) IR remote.

# keypress home
# keypress right

I tried to keep the script simple to update or modify, and plan to write a partner script for some of the more advanced features listed on the wiki page, and perhaps a few more.
