For some odd reason I had to change Peter’s second one to:
for i in *.mpeg; do mv “$i” “${i%mpeg}mod”;done

(I’m changing mpeg extensions back to mod so I convert them to dv files for Final Cut Pro X)
Oh, using Mac OSX Lion

By far the best, quickest ánd cheapest solution to change file extensions in batch on a Mac! Thanks!!

this is not worth a shell script — just type it in by hand

for i in *.txt; do mv $i `basename $i .txt`”.xml;done

of course, that doesn’t handle spaces right, so fix up the rest

for i in *.txt; do base=`basename “$i” .txt`; mv “$i” “$base”.xml;done

To work with spaces, put ” in line 28, so it will be:

mv “$filename” “${filename%$1}$2″

This doesn’t work if there are spaces in the file names, like in music
