The best way is not to use spaces in filenames; underscores perform their purpose very well without making things more complicated. :-) To iterate over files, I would not use `ls`, instead, I would let the shell do the expansion of * for me, as it has already been suggested. Because the file names x iterates contain spaces, be very (!) careful to assure that the applications you call with these filenames get the spaces correctly masked, either put the filename in quotes or substituts " " by "\ ". You would have won nothing when the application you call with the filename interpretes it as an argument list with two elements. for x in *; do echo "${x}" done Replace the middle line with any program call you want. -- Polytropon >From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
