Re: Check for an empty file

You could use Perl's -s instead of the shell's.

if (-s "/home/vcg/Documents/Trial/temp")

Note that empty (-z or !-s) and non-existent (!-e) are different things.

Thanks! It's working great! I'd prefer not to use the shell if I can help it!	[reply]

I had some trouble with this a while back. -s returns a zero if the file is either zero bytes or nonexistent. It got a bit confusing until I worked out what was happening.	[reply]

Actually, it returns undef (and sets $!) if the file is non-existent.	[reply]
