(if you are not familiar with it, this may look a bit cryptical, but there is nothing to it. the backticks mean: evaluate the expression within. and the expression says: echo $filename | sed s/wav$/mp3/, which means: feed the filename to the regular-expression-based replacement, which replaces 'wav' at the end of the line ($) with 'mp3') > 2. I can export to ogg format from audacity. Can I do the same thing as > (1) for this as well? Does ogg format support tags. almost the same with oggenc, except oggenc wants the output file with -o for filename in *.wav; do oggenc -o `echo $filename | sed s/wav$/mp3/` $filename; done note that the above will fail if your filenames contain spaces. ls *.wav | while read filename; instead of for filename in *.wav would deal with that. but as always, there are many other ways to do the same thing. this is\ just how i would do it. maarten
