Hi Erez
You may also be surprised to learn that all perl features are well documented.
You get the index with "perldoc perl", and the page referring to the one you
needed "perldoc perlvar".
I'd recommend reading all the online docs as they describe all the features of
the language.

I'd suggest placing your pipeline of commands into a bash shell script and
running it manually from the command line and carefully observing it running.
That way you are then dealing with a known quantity outwith any Perl issues.
As someone else replied, consider using the "qx" command rather th

a book thats good show respect to the author ande purchase a copy.

Hi
From my experience after reading what has been suggested is to try and do some
real examples which test you knowledge to the limit.
What is the difference between a Basic Regular Expression and an Extended

Here's another way, but not necessarily the best Perl, but it does work:
#!/usr/bin/env perl

use warnings;
my @filelist=;

my ($file, );
foreach $file (@filelist) {

The program is called "screen" just in case you are looking fo it. The first
sentence from the man page says
"Screen is a full-screen window manager that multiplexes a physical terminal
between several processes (typically interactive shells)."
On Linux I also use Ctrl-Z whrn in vim to go o
The following Perl one-liner will do what you need
perl -n -e 's/(.{8,8}).(.*)/$1$2/;print ;'
The first set of parentheses strips out the first 8 characters, the second set
strips out everything after the 9th character which is lost.
My test line was:-
(echo "1234567890";echo "abcdefghijkl")|pe
Hi Arun
You didn't say what you really wanted to achieve. Do yo want to dabble and
learn from that experience what using network modules is all about ?

Hi
This will do what you want:-
perl -le '@test=(1,2,3,4,5);print join "\n",@test;'
The -l option ensures a final newline after the last element of the array is
printed. The order of the options is important as changing it to "el"
wouldn't

Hi
Unless Perl is the only tool available to you in your toolbox and if you're
running Linux or similar consider the "tr -s " command in a shell. However if
you are
strictly limited to Perl then this stand regex works:-
echo ","|perl -ane 's/,*/,/;print'
Try it by cutting and pasting it.
