来自.cshrc的源.bashrc

Question

Is it possible to source a file from in a session? I'm asking because tcsh is our default shell at work and the .cshrc has to be used to set up the environment initially.
However, I am not really familiar with the tcsh and I have my own set-up in bash, so right now I have the following lines at the end of my .cshrc file:

if ( $?prompt && -x /bin/bash) then
  exec /bin/bash
endif

This works fine, loading my environment from .bashrc and giving me a bash prompt for interactive sessions but now I also need the same set-up for non-interactive sessions, eg to run a command remotely via SSH with all the correct PATHs etc.
I can't use 'exec' in that case but I can't figure out how to switch to bash and load the bash config files "non-interactively".
All our machines share the same home directory, so any changes to my local *rc files will affect the remote machiens as well.

Any ideas welcome - thank you for your help!

Answer 1

If $command is set there are arguments to csh , so it is a remote shell command. This works for me in .cshrc :

if ($?command) then
  echo Executing non-interactive command in bash: $command $*
  exec /bin/bash -c "${command} $*"
endif
echo Interactive bash shell
exec bash -l

Test:

$ ssh remotehost set | grep BASH
BASH=/bin/bash
...

proves that it ran in Bash.

Answer 2

After some more research I'm now quite sure that this won't work, but of course feel free to prove me wrong!

To load the environment in bash I have to switch to a bash shell. Even if that is possible "in the background", ie without getting a prompt, it would still break any tcsh commands which would then be attempted to execute under bash.

Hmmmm, back to the drawing board...
