in thread Watch log for string (tail -f)

That was a typo and I have fxed it. I'm still not getting any idea abou7t how to do this, and how to break out the tail -f?

This is what I got so far:

#!/NMS/perl/ACTIVE/bin/perl -w use warnings; use strict; #variables my $currentDate = `date +%Y%m%d`; my $logPath = "/logs"; my $logFile = "$logPath/log.$currentDate"; my $ipaddress = $ARGV[0]; my @tail = `tail -f $logFile | grep $ipaddress`; #print "Log file: $logFile\n"; #print "IP address: $ipaddress\n"; # script begins if (@tail) { my @lines = $tail[0 - 2]; print @lines; exit(0); } else { print "not found"; exit(1); }

    I think you will need to use the file handle with the while loop as the other posters have suggested. Have you tried this?
