$ rm -rf directory || true

Useful Options / Examples

true

This just logically evaluates to true. This is most useful in scripting

while true
do
   echo 'infinite loop'
done

rm -rf directory || true

This is useful because sometimes we want to make sure that a command that could end with an error will return with exit status zero, to make sure that a script will continue running.
