What do you mean?! Save this code to a file and test it. `#!/usr/bin/perl -wl use strict; open my $fh, '>', '/tmp/test.log' or die $!; print $fh 'STDIN ', ( -t STDIN ? 'IS' : 'is NOT' ), ' available' or di +e $!; close $fh or die $!;` [download]	[reply] [d/l]

In a cron job -t would evaluate to false which in my case would mean my script would think info is being piped to it when I have a commandline option -logfile <file> being used to specify input.	[reply]

You seem to confuse the meaning of `STDIN`. In "filter" mode, `STDIN` won't be the terminal, e.g. `echo 'foo' \| ./test.pl`	[reply] [d/l] [select]
