Why on earth would you want to put ls in backticks? I wonder who originated this rather redundant and fragile (what happens when a filename has any form of whitespace?) construct? Try googling for "useless use of cat awards" for another redundant construct that people love to use. for f in *.bmp ; do convert $f --to-jpeg ; done But even better than the above is just: mogrify -format jpg *.bmp You can probably also (untested): convert --to-jpeg *.bmp -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
