Re: Re: one-liner hogs

For disc overflows:

not perl, but works:

cat /dev/zero > /tmp/.#overflow#
[download]

Of course, could also be

perl -e 'open T,">/tmp/.#overflow#";open F,"</dev/zero";while(<F>){pri
+nt T;};'
[download]

Or the 'smarter'(?) way to completely overflow a machine (but probably only as root):

perl -e 'open M,"/sbin/mount|grep -v':'";while(<M>){($m)=split($_);if(
+fork){open Z,"</dev/zero";open F,">$m/.#overflow#";while(<Z>){print F
+}}};'
[download]

But that's WAY too much to memorize, da?

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>;` [download] 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]
