WOW!
Tom Are you trying to frighten me?
Your doing a good job, ;->
Listen buddy thanks a million, I do appreciate the input the file in question
had a list of mp3's which had been renamed removing the funny characters from
the names and we eneded up with several text files containing lists of mp3
sorted into various categories, the problem was we could tell if we missed
any. So I created a directory for each text files content eg rave, rock,
solo, alternative etc....
Then I ran this.
for i in `cat text_text_file`; do
mv $1.mp3 /dest/dir
done
however it failed as I had gotten confused and was in the wrong dir. This
hapens when you constantly switch terminals ;->
anyway we are all done now and have discovered that there are very few left to
sort.
Thanks again friend,
I would like to learn how to script like you though. ;-)
