Hello,
I suggest this:
#!/usr/bin/perl -w
use strict;
my $var1 = "23456789";
my $var2;
($var2 = $var1) =~ s/(\d)/$1 /g; # only add 'g' for global substitution
print "var1 = '$var1', var2 = '$var2'\n";
Regards.

try this:
#!/usr/bin/perl -w
use strict;
my $if = "path_to_input_file";
my $of = ">path_to_output_file";
my ($name, $addr);
open(IF, $if) or die "Can't open file $if for reading\n";
open(OF, $of) or die "Can't open file $of for writing\n";
while () {
chomp;

Hi,
the second line is simply declaring two variables:
1 - the scalar $itemtype
2 - the hash %symbol
just another way to say
my $itemtype;
my %symbol;
no magic here, *NOT* a list or data structure.

Hi,
try this :
#!/usr/bin/perl -w

print "param is $_\n";

Hi,
when you get $s from STDIN, it comes along with a newline,
so try something like: chomp($s = );

Hi, all
Do someone knows about a perl module to convert PDF files to postscript
?
I'm working on several UNIX (AIX) boxes and want to 'automagically'
print PDF files.
Thanks.

Hi,
try this :
my $last = (glob("fred.*"))[-1];
---
- $last gets the last item in the array returned by glob()
- glob() returns file names sorted alphabetically ;-)
Regards.

Hi, Alex
i suggest the following:
#!/usr/local/bin/perl -w
my $filename = "Your_file_name";
# if you are so lucky to work on Unix
my $lastline = `tail -1 $filename`;
print $lastline;
# if file is small enough to hold in an array
open(FILE, $filename) or die "Can't open $filename.\n";
my @array
Hi, James
Can you post some examples ?
- what do you call the header in your files,
- what string(s) are supposed to match what,
- what is the data to write to output file(s)
and so on...
Rgds.

Hi,
$num += $num % 2;
this increments $num if $num modulo 2 is 1
(ie. if $num was odd)

Hi,
I've downloaded Tie::File module from
http://search.cpan.org/author/MJD/Tie-File-0.93/
and given it a little try : works fine.
(even for me : Just Another Perl Newbie).
Thanks, José.

Not an expert in perl (nor in english), but let's try ;-)
if your output file is not supposed to get too big,
consider 'writing' first your output lines in a hash
... $hash{1} = "line 1"; and so on
(later, writing line 10 for eg.)
if (whatever)
{
$hash{5} .= " these few words";
}
when finished,
If you are generating the email CGI form on the fly,
you can pass the number as a hidden INPUT field :
eg:
... INPUT fields as needed
Hope it helps.
