Here is a downloadable version of Perl tutorial in PDF or HTML.

BTW, I get several errors when I try to run perl on my systems. Here is the program.

# cat myprog.pl
#!/usr/contrib/bin/perl

use strict; # important pragma
use warnings; # another pragma
print "What is your username? "; # print out question
my $username; # "declare" a variable
$username = <STDIN>; # ask for a username
chomp($username); # remove "new line"
print "Hello, $username.\n"; # print out the greeting

*** Here are the errors.


# ./myprog.pl
Can't locate strict.pm in @INC (@INC contains: /opt/perl5/lib/5.00502/PA-RISC1.1

Here is my version of PERL.

# perl -v

This is perl, version 4.0

$RCSfile: perl.c,v $$Revision: 4.0.1.8 $$Date: 1993/02/05 19:39:30 $

My favorite site for perl type info is http://www.perlmonks.com/.

1) update your perl version. use the most current stable 5.8 i believe and your problem is solved.

2) according to your error your version of perl does not have the perl module for strict installed.

you can get perl modules from www.cpan.org very easy to use and navigate after you familurize yourself with the site.

also note that you should use #!/usr/bin/perl -w

when perl is installed it installes the binarys in a few locations and one copy is in /usr/bin. the -w switch is the warnings switch. just a bit easier instead of defineing the use warning; pragma

Thanks Perderabo, it works now. Although I don't need the strict or warning lines, they err out.

My latest version available for HPUX from my internal depot is:

perl B.5.6.1.C Perl Programming Language

here's what I get after loading.
# perl -v

This is perl, version 5.005_02 built for PA-RISC1.1

[hostname]/home/i_am_anti_coolness$perl -v

This is perl, v5.8.0 built for sun4-solaris

I can only assume you checked the actual homepage of perl for the most current stable release?

either way 5.6 i know has the strict.pm (solaris 8 by default ships w/ 5.4 which has strict.
