(ref. utime(2)) OK, fine, than the touch man page should say BUGS The optional timestring doesn't work if you don't own the file, even though you can write to it. In that case consider copying the file, touching it to the preferred date, moving it to the original file name, if possible, then chown(1) and chgrp(1)ing the file to the original owner. [I haven't considered any of the options letters.] [Also thanks to Sam Ho] -- Dan_Jacobson@ATT.COM Naperville IL USA +1 708-979-6364
