Thanks everyone! I have a much better understanding of what's going on
now and am on my way. Feel pretty silly about the barewood thing. I
need to keep my glasses on. :)
I'm working on something else right now so I won't be able to try all

Hi,
I'm a perl newbie and would like to ask this question here.
Let's say I have the following code. Trying to check the disk space,
it's to truncate the percent sign % from the df -k output, compare the
percentage field to see if it's bigger than 90%, and grasp only those
lines that are and
Ok, I think I more or less have it. The true grocking of the hash,

Hi All,
I got a problem while installing the module with *CPAN.pm* shell. At the
begining, it was asked to for some confiuguration settings. It could able to
find almost all settings except make. At first, I ignored that and moved to
install the modules but it is saying like the make test failed.
Try to use this way,
use strict;
my $percent=90;
my @df;
open(DFOUT, df -k|);
while (DFOUT) {
next if /Filesystem/i;
my ($free) = /(\d+)%/;
if ( $free = $percent ) {
push(@df, $_);
}
}
close DFOUT;
print @df;

be nice to yourself and allways use strict;
and don't call subs with , unless you know why you need .
hopefully you can avoid some problems when you're writing perl code.

i am trying to figure out how to use the subroutine in a library now.
so I did this.
I name one script sub.pl and the library sub-lib-pl:
the script.pl contains:
#!/usr/bin/perl
use strict;
require 'sub-lib.pl';
marine();
The sub-lib.pl contains:
#!/usr/bin/perl
sub marine {
$n += 1;
2007/8/30, Amichai Teumim [EMAIL PROTECTED]:
I get the error:
sub-lib.pl did not return a true value at ./sub.pl line 5.
Why is that? The value is 1 isn't it?
to add 1 at the end of sub-lib.pl,it would work.
echo 1 sub-lib.pl
when 'require'ing a file,perl need it to return a true value.
Yeah that works now. Great. Finally I'm getting this...after months. Thank
you.

That's rubbish,
You can call a sub before you create it as you say. At compile time the
entire code is done (bar some exceptions)
The issue here is drop the unless you really know what it does
my($n);

sub marine {
$n += 1;
print Hello, sailor number $n!\n;

Works fine.

thats because you're not using perls prototyping feature at all.

Dear Folks,
I need to print diagnostic message strings like:
warn $parent/$child does not exist: verification failed\n;
in conditional blocks that are nested and indented. This means that, on
occasion, the message string overflows to the next line in an 80-character line
in my source file.
Is there a way to dump the HTML code for a web page? I need to write
a script which will collect and summarize content from intranet web
pages. By dump, I mean to read it the same way you would read a file
and parse its contents. Thanks.
