In any case, this being UNIX, there's ways to hedge your bets... I'd make an 'out' folder and create links in it, instead of renaming the original files. If something goes wrong, you're not left with all your files irreparably misnamed, just a bit of trash you can delete and start over.

Code:
#!/bin/bash
mkdir -p ./out/

exec 5<filenames
exec 6<filetitles
while read LINE FILENAME <&5 && IFS=$'\t' read NUM FILETITLE <&6
do
        if [ "$NUM" -ne "$LINE"]
        then
                echo "Numbers do not match?"
                continue
        fi

        FILETITLE="${FILETITLE//$'\t'/ - }" # Change tab into ' - '        
        ln "$FILENAME" out/"${NUM} ${FILETITLE}"
done

exec 5<&- # Close files
exec 6<&-

This should create links in the ./out/ folder of the right names.

Thanks, the files originate from an old audio tape archive which at one point has been digitized. The textfiles where created a long time ago on a separate system.

I will have a look at your script – thank you.

Remove the echo command if happy with the proposals.
That seems to work about right.
I have two problems though.
The filenames looks like this:
03 ELO---Happy-Haunting

But I would prefer:
03 - ELO - Happy Haunting

I need some sort of separation between the thre fields which are track number, artist, title.
If blanks needs to be converted then perhaps underscore is better? Like: " 02_-_artist_-_title_song.wav"
I could easily convert underscore back to space afterwards.

Is this the section where blanks are converted?
Quote:
${NFN// /-}
Also, it seems like some folders have their files numbered like this:
01 fsfsdf.wav
02 dfgh ert.wav
...
11 abc def.wav

Leading zeroes below ten. Where do I modify the script for this?
