perl_req has asked for the wisdom of the Perl Monks concerning the following question:
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);
