I have to burst in here and simply state that I think that's
possibly the single least correct statement I've seen on 
this newsgroup ever.

Most linux setups I've seen have had ls sanitise its output 
and filter out control characters. To examine what was filtered,
you could use ls -b to have them escaped instead.

If in doubt, simply prefix filenames with './'. That declaws
practically everything.
