How to lock a terminal

[Nick Warne]

Hi Everybody,

I ma not sure if this is a bug, or if it is what causes it - if it 
isn't, then it is me being stupid.

I was in a SSH session, and checking something inadvertently issued:

> nano /var/log/messages | grep a

(I was searching for something else than an 'a', but the above example 
shows the issue - about to use 'nano', but then forgot to change it to 
'cat').

The terminal just sits there doing nothing - CTRL+C doesn't do anything; 
in a SSH session, the only option is to kill the terminal.  On a local 
machine, you can use kill -9 from another terminal to get out of it.

I don't know if this behaviour is expected or me being stupid, or 
something else going on.

Regards,

Nick
