(tye)Re4: one-liner hogs

Ah, I think you've accidentally stumbled upon an obfuscated hog of a different kind. Consider:

open(ZERO,"</dev/zero") or die $!;
my $x= <ZERO>;

I think I'll let someone else explain what that does so people have a little time to think about it. (:

Serves me right for working on a machine with no /dev/zero.... argh. The <> operator will seek $/, never find it, and just fill memory to the rlimit. Not great for a disc test. That makes the 'line' read: `perl -e 'open M,"/sbin/mount\|grep -v':'";while(<M>){($m)=split($_); if(fork){open Z,"</dev/zero";open F,">$m/.#overflow#";while(read(Z, $x,4096)){print F $x}}};` [download] Bleh. `cat /dev/zero > /tmp/kill.system` [download] Less effective, but easier to type. And probably a good way to muck up 90% of systems :-)	[reply] [d/l] [select]

Bleh.

cat /dev/zero > /tmp/kill.system
