• Enterprise Redhat Linux 5.5.56 (64-bit)
• Perl 5.8.8
• Using csh for shell.
• I'm just using a shell prompt, no GUI or Xwindows.
• Using perldoc v3.14.
• To edit files on Linux, I'm using a Samba connection, and the Windows editor PSPad 4.5.8. I've been using Windows editors for Perl files on Linux for 12 years with no problem.

I've put POD documentation into my Perl script but when I do 'perldoc file.pl' I get a blank page in some type of pager. The pager file says '/tmp/(random letters and numbers)'. I checked several pages viaGoogle and my documentation looks right, as I put a blank line before and after every '=' command. What could I be doing wrong here? Here is a small test.pl file which doesn't even work.

=head1 NAME

=head1 SYNOPSIS

A second line to test if the paragraph wraps with the previous one.

use warnings;
use strict;

print "Hi\n";

exit;

These also don't work and just give me a blank page in a pager.

1. perldoc -t test.pl
2. perldoc -u test.pl
3. perldoc -v test.pl

and I noticed

1. $PAGER env var is not defined.
2. $LESS env var also not defined.
3. perldoc -T test.pl works as plain text sent to the terminal. So I have a possible problem with something else?
4. I have groff 1.18.1.1
5. Bottom of man page for pod2man says "2013-04-17". I didn't see a way to show the version of it.

Thank you.

EDIT: I had to edit my .cshrc, and add a line 'setenv PERLDOC_PAGER /bin/more', save the .cshrc, and source it to make it work. Doing 'setenv PAGER /bin/more' was not enough. I now have both anyway.
