For disc overflows:
not perl, but works:
cat /dev/zero > /tmp/.#overflow#
Of course, could also be
perl -e 'open T,">/tmp/.#overflow#";open F,"</dev/zero";while(<F>){pri
+nt T;};'
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
+}}};'
But that's WAY too much to memorize, da?
