Hello Andrew, thanks for your answer.
I tried to do this way:
*#!/usr/bin/perl -w
$res = qx/whoami/;
print $res;
print "-----------------\n";
if ($res eq "daniel"){
print "Welcome, ".$res." how are you?.\n";
}else{
print "Your name isn't daniel\n";
}*
when I executed this script I receive this output:
[EMAIL PROTECTED]:~/Desktop$ perl teste.pl
daniel
-----------------
Your name isn't daniel*
What I did wrong? The script output doesn't should be "Welcome, daniel how
are you?"??
PS: Sorry by my English. I'm not a good speaker... I'm learning yet.
