ssh autocompletion in tcsh

I wrote the following for my .tcshrc to get some autocompletion for ssh.

set hostlist=(`cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | cut -f 1 -d ',' | uniq`)
complete ssh 'p/1/$hostlist/' 'p/2/c/'

Determine the current runnning shell (linux)

echo $SHELL

bash startup

In interactive mode bash executes some startup scripts. First thing to know is if it is a login shell or not a login shell: 

* login shell: (executes more things)
(1) general settings for all users are in: /etc/profile
(2) personal settins may be in: (first one readable)
~/.bash_profile
~/.bash_login
~/.profile
(3) before logout: ~/.bash_logout

* non-login: 
>bash => ~/.bashrc

>bash --norc => nothing
>bash --rcfile filename => specify another rc file
