Don't forget to check the return value of your open call. To wit: `open FILE, ">bob.txt" or die "Could not open file: $!\n";` [download] $! is a special variable that returns the error. It'll tell you why you couldn't open the file.	[reply] [d/l]

Opening a file for writing that does not exits creates the file. grin so `open FILE, ">bob.txt";` [download] Crulx	[reply] [d/l]

If you want to check whether the file already exists before you clobber it, then use the -e test thusly: `$name = "filename"; if (-e $name) { print "File $name already exists.\n"; } else { do stuff; }` [download]	[reply] [d/l]
