Hello,
I am still very very new to perl and hope such
a newbie question will go un-punished.
I get emails consisting of 3 lines in the body
that are generated by this command....

(uname -a ;uptime ;date) | mail -s uptime time@taproot.bz

I have made a little code that opens the user "times" mail
spool and grabs the next 3 lines after a blank line, this
is to cutout the header and grab the output of the uname
stuff. The script works...i guess, but complains about
Use of uninitialized value in string at ./mail.pl line 15.

Im guessing that the blank line after the body is producing
this....line 15 is trying to call up three more vars
from the @array that are not there when only one mail is
present.. or dealing with the last mail in spool ..
I think.
#! /usr/bin/perl -w

$file = "/var/spool/mail/mohadib";

open(MAIL, "$file") || die "cant open spool\n";
@array = <MAIL>;
close (MAIL);

foreach $array (@array){
        if($array !~ /[A-Za-z0-9]/){
                @num = (1 .. 3);
                foreach $num (@num){
                        $current = $new + $num;
                        print "$array[\"$current\"]";
                }
        }
        $new++;
                
}

could someone put my logic on the right path :)
maybe I can test for the words Linux or BSD in the
next line after i have matched a blank line
....and exit if not true?
Hope this is coherent,
jd
