Vadik,

I notice your script stops and waits for each track before proceeding to
the next. This is inefficient, as ripping is an I/O bound task and
encoding a CPU-bound one. This is a perfect opportunity for multitasking.

Here's the script I use :-)
	~Ben



#!/bin/csh -f

set prog="$argv[1]" # program to encode mp3s with
set dir="$argv[2]" # dir in which to store mp3s
set tracks=(`cdd |& awk '/^ *[0-9][0-9] *CD-AUDIO *[^ ]* *[^ ]* *[^ ]* *[0-9][0-9]:[0-9][0-9]:[0-9][0-9] \/ [0-9][0-9][0-9][0-9][0-9][0-9] *[0-9]+ *$/ {print $1}'`)

foreach i ($tracks)
	if(!(-e ${dir}/track-${i}.mp3)) then
		if(!(-e ${dir}/track-${i}.cda)) then
			cdd -a -t $i $dir >& /dev/null
		endif
		wait
		($prog ${dir}/track-${i}.cda ${dir}/track-${i}.mp3;rm ${dir}/track-${i}.cda) &
	endif
end

wait
