Source by bashrc when I exit an 'ssh' session

Question

I'm on OS X and am using iTerm2.

I've updated my Bash profile on several of my servers so that when I ssh into them I can tell at a glance from the tabs what boxes I'm on. When I exit from an ssh session, the shell that initiated the ssh session does not source ~/.bashrc again (which I understand to be normal operating procedure), so my tab titles and colors persist with the titles and colors they were from my ssh session.

Normally when I exit an ssh session, I will also exit the shell on the computer that I'm physically using as well. But for consistency's sake, I would like to revert my iterm2 tabs to the appropriate titles and colors for the shell they represent when I exit an ssh session.

Is there a way to source my .bashrc when I exit an ssh session?

In all of ~/.bash_profile, ~/.bashrc, and ~/.bash_logout I have the following lines:

export PROMPT_COMMAND=''
echo -e "\033];test machine name\007"

When I exit an ssh session, it looks like none of these Bash files in my home directory are sourced to reprint the tab title. When I manually source them with source ~/.bashrc the tab title reprints just fine. So, the syntax is not wrong.

Answer 1

If you want this to be command-specific, then redefining ssh (as mentioned in another answer) is probably the best approach.

If you actually prefer something more general, bash has a PROMPT_COMMAND shell variable you can set to run a command (or multiple commands) before the shell prompt is printed, which would happen right after ssh (or any other command) returns to the shell.

Yes, define a shell function:

ssh() { command ssh "$@"; source ~/.bashrc; }
