Overthewire Bandit Level 18 To 19

Level goal

The password for the next level is stored in a file **readme** in the homedirectory. Unfortunately, someone has modified **.bashrc** to log you out when you log in with SSH.

This one caused me sadness, after some digging..

bandit17@bandit:/home/bandit18$ ssh -t bandit18@localhost cat readme

 -t      Force pseudo-terminal allocation.  This can be used to execute arbitrary screen-based programs on a
             remote machine, which can be very useful, e.g. when implementing menu services.  Multiple -t options
             force tty allocation, even if ssh has no local tty.

VICTORY.
