how to tell if STDIN is a tty

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I'd like my perl program to realize that STDIN is not a tty and adjust if that's the case, without being told in any other way that that's the case. Is there a way to test a filehandle for its being a tty? Much thanks in advance, Greg

The `-t` filehandle test should do just fine. `japhy` -- Perl and Regex Hacker	[reply]

or the POSIX way: `use POSIX qw/isatty/; something() if !isatty($handle);` [download] AgentM Systems nor Nasca Enterprises nor Bone::Easy nor Macperl is responsible for the comments made by AgentM. Remember, you can build any logical system with NOR.	[reply] [d/l]
