in reply to how to use angle operator with timeout?

I couldn't get alarm to work for me in a consistent manner, so I tried Tie::Scalar::Timeout.
#!/usr/bin/perl -l use strict; use warnings; use Tie::Scalar::Timeout; tie my $line, 'Tie::Scalar::Timeout', EXPIRES => '+1s', POLICY => undef; $line = system("whoami"); while (defined($_ = $line)) { foreach $line(my @lines) { print "$_" or die $@; } }

[erix]: it has TOP, IIRC
[Corion]: erix: Ah. I use where 1 = 0 for queries where I only am interested in the structure ;)
[erix]: 1=0 is as short as TOP :)
