I have a requirement to process a folder full of files (converting .avi to .mp2 and .m1v, as it happens, en route to DVD authoring). To convert a single file I use the command line
lav2wav +p foo.avi | mp2enc -V -o foo.mp2
I find the whole area of regular expressions etc confusing; is there a kind expert who could show how to get the above to work for all the files in a folder, such as
for name in *.avi do (How would I do the above with each file?) done
In particular, how do I match just the filename and leave off the extension?

No regular expressions required. This is a search and replace for bash.

In general, you can use the basename command to do that, but using bash's replace is faster for your problem (no extra processes needed).
; basename test.c .c test
