Hi All, I am looking for a certain string from a huge log file for approx 1000 ID's. The log file is in a text format. Each log file is separate for each ID and the no of lines each has varies. With the code I have written it goes into each log file, looks for that particular string. When it does not find anything it does not print anything. But once it hits the string I am looking for it keeps on printing the same string for all the other ID's. Any help will be greatly appreciated. My code is as below:

$messages = "N/A";
open(MYINPUTFIL3, "file path");

while(<MYINPUTFIL3>){
chomp;              
 $SYS=$_;

 $SYS =~ s/\r|\n//g;
                                                
if($SYS =~ /search string/i)
 { 
         $message_1=$SYS ;          
         $message_1 =~ s/\r|\n//g;
         $message_1=~ s/^\s+//;
         $message_1=~ s/\s+$//;
         $message_11 = $message_1;
         $message_12 = $message_1;
         $message_12 = s/[^a-zA-Z]*//g;
         $message_11 =~ s/[^0-9.]*//g;
     last;
                             
}


}
close MYINPUTFIL3;

print "$message_1\n";
open(FILEWRITE, ">>trial_one.txt");
print  FILEWRITE  "$message_1\n";
close (FILEWRITE);
