I'm trying to work out how to get SSH to run a script before passing a shell to me. The reason for this is that I will be logging into shared users on many boxes and I want my own configuration when I log in. It would not be appropriate to put my own environment variables and aliases into .cshrc, not least because of the number of different users on different boxes that I will be logging in to.

So let's say I have my script with various alias and setenv commands at /home/adam/my_script and I want it to be sourced when I log in.

I've tried using:

ssh user@server1 'source /home/adam/my_script; tcsh'
ssh user@server1 '. /home/adam/my_script; tcsh'

and also this:

ssh user@server1 /home/adam/my_script
ssh user@server1 'csh -c /home/adam/my_script'

when tcsh (without an ampersand) is at the bottom of my_script, but no combination works as you expect. Either the environment variables and aliases don't exist, or the shell will behave strangely, like there is no line input prompt.

What am I doing wrong?

    I would think this should work: ssh -t user@server1 'source /home/adam/my_script; tcsh' -- add -t – glenn jackman Dec 9 '14 at 16:12
  • The environment variables work but it appears that the aliases don't. I guess they're not inherited by child shells? – Doddy Dec 9 '14 at 16:24
  • You'd have to check your tcsh man page. What I do in a similar situation is edit the .bashrc to add a function that sources my config script. So I log in, type jackman and I'm set up. – glenn jackman Dec 9 '14 at 16:27
