The Lounge What is on Your Mind? Most deadly commands on Unix/Linux !! Post 302337471 by encrypted on Friday 24th of July 2009 08:05:45 AM
Old 07-24-2009
Few years ago after leaving this telecom vendor I was working
with one of my colleagues who was with the application team IMed
me and asked for help to delete a directory with a & at the end.
The command I told him was:
rm -rf dir\&
which in the most bizzare way got translated by him to:
rm -rf dir /&
This would have caused minimal damage had this not been run as root
user and on the main database server with terabytes of data
on it..What happened next is anybody's guess Smilie

Object::Deadly::_unsafe(3)				User Contributed Perl Documentation				Object::Deadly::_unsafe(3)

NAME
Object::Deadly::_unsafe - Implementation for the deadly object METHODS
"$obj->DESTROY" The DESTROY method doesn't die. This is defined so it won't be AUTOLOADed or fetched from UNIVERSAL. "$obj->isa" "$obj->can" "$obj->version" "$obj->DOES" "$obj->import" "$obj->require" "$obj->use" "$obj->blessed" "$obj->dump" "$obj->peek" "$obj->refaddr" "$obj->exports" "$obj->moniker" "$obj->plural_moniker" "$obj->which" "$obj->AUTOLOAD" Each of AUTOLOAD, a named list of known UNIVERSAL functions and then a query for everything currently known are all implemented with "Object::Deadly->get_death" to prevent anything from sneaking through to a successful call against something in UNIVERSAL. That list of functions are what core perl uses plus a bunch from CPAN modules including UNIVERSAL, UNIVERSAL::require, UNIVERSAL::dump, UNIVERSAL::exports, UNIVERSAL::moniker, UNIVERSAL::which. That's just the list as it exists today. If someone else creates a new one and you load it, be sure to do it *prior* to loading this module so I can have at least a chance at noticing anything it's loaded. SEE ALSO
