Hi there, I found what I think is a bug in the *md5sum* command. When used on a filename with a backslah, the output doesn't look quite the same as usual: # ls -l /tmp/file1 '/tmp/file\2' -rw-r--r-- 1 root root 2 2012-04-30 17:05 /tmp/file1 -rw-r--r-- 1 root root 2 2012-04-30 17:05 /tmp/file\2 # md5sum /tmp/file1 '/tmp/file\2' 60b725f10c9c85c70d97880dfe8191b3 /tmp/file1 \3b5d5c3712955042212316173ccf37be /tmp/file\\2 Hope this helps ------------------------- *Santiago DIEZ* *Director *CAOBA Support team ------------------------- ------------------------- *Quark Systems & CAOBA* *23 rue du Buisson Saint-Louis, 75010 Paris* -------------------------
