The code below is from a cgi-script from a prior admin. In this sub the section for tail with grep does not display back. It seems the grep command is not working. I did remove the pipe grep from the line to make sure the if logic was working. it will display the logs, but if I try with the grep line and give it a host it will not display. I need a kick start. 

#####
sub tail_file {
my $node = shift;
my $command = ();
if ($node =~ /all nodes/i) {
        $command = "tail -100f $logdir/syslog";
}else{
        $command = "tail -100f $logdir/syslog | grep -i $node";
        }
my $count = 0;
print "<h2>Tailing /var/log/syslog...</h2><br>\n";
open (TAIL,"$command |") or die "Can't open TAIL($command):$!\n";
while ($count <= $max) {
        chomp(my $line = <TAIL>);
        $line =~ s/\s/$space/g;
        print "$line<br>\n";
        $count++;
        maxed_out() if $count >= $max
}
}
