Hi Experts, Forget my last question post. I've managed to get it done. Not sure if i got it done 'intelligently' though. =P Can anyone please advice on this instead? Based on the current code below, how do i EXCLUDE extracting lines that contain any of the array of names defined, although strings 'gateway' & 'timestamp' are found in the particular line? E.g. ## To exclude extracting lines with username 'andrew' ## dcndksckdsnckdc gateway jdscjscjsdh timestamp andrew dkcd 
print "Specify full directory of logfile.\n"; 
$file = <STDIN>; 
chomp $file; 
 
print "\nIdentified file is $file\n"; 
print "Is this correct? (y/n)\n"; 
$confirm = <STDIN>; 
chomp $confirm; 
 
 
if ($confirm eq "y") { 
    print "\nCommencing work on $file.\n"; 
    workings(); 
} else { 
    print "Terminating program...\n"; 
     
} 
 
## Subroutine to open & read logfile 
sub workings {  
    print"In Subroutine workings now.\n"; 
    open (LOGFILE, $file); 
    print "Opening logfile...\n"; 
    open (OUT, ">>", 'D:\Temp\test.txt') or die "$!"; 
    print "Opening output file...\n"; 
    print "Checking for string GATEWAY...\n"; 
    while (<LOGFILE>) { 
        if (/gateway/) {  
            $count = $count + 1; 
            print OUT; 
            print "Extracting line ...\n"; 
        } elsif (/TIMESTAMP/) { 
            $count = $count + 1; 
            print OUT; 
            print "Extracting line ...\n"; 
        } 
    } 
    print "\nTotal of $count lines extracted.\n"; 
    close OUT;  
    close LOGFILE; 
}
