determining OS

Hi All!

I have a script (perl v5.8.5) that needs to run on both AIX and
linux. Does anyone have a code snippit that would allow the script
to determine which OS it is currently running under? Any help would
be greatly appreciated!

Thank you!
Greg

RE: determining OS

Try the following on each of the machines.

perl -w -e 'print $^O, "\n";'

You can try read the $^O variable:

print $^O; #Mine is MSWin32.

As others have mentioned, $^O will probably be good enough to
distinguish between those OSs (see 'perldoc perlvar'). Run the following
command on each platform to tell you what to look for:

perl -e "print qq{$^O\n}"

If you need more detailed, or finer grained, platform dependent
information use the Config module (see 'perldoc Config').

Re: determining OS

Thank you to all that responded. The variable $^O was exactly what I
was looking for.

Thanks again,
Greg



Hi All!

I have a script (perl v5.8.5) that needs to run on both AIX and
linux. Does anyone have a code snippit that would allow the script
to determine which OS it is currently running under? Any help would
be greatly appreciated!

Thank you!
Greg
