in thread How to set timer in perl

hi,

Here is the code which i have tried.

#!/usr/bin/perl -w use strict; my $FH; local $SIG{ALRM} = sub { die "Timeout no data received\n"; }; open ($FH, '<', "file1") or die "cant open file to read file$!.\n"; alarm 5; while (<$FH>){ if ($_ =~ m/any string/i){ print "$_\n"; alarm 0; } } close ($FH);
