How do I execute a command every time after ssh'ing from one machine to another?

How do I execute a command every time after ssh'ing from one machine to another?

e.g

ssh mymachine
stty erase ^H

I'd rather just have "stty erase ^H" execute every time after my ssh connection completes.

This command can't simply go into my .zshrc file. i.e. for local sessions, I can't run the command (it screws up my keybindings). But I need it run for my remote sessions.

From stackoverflow
  • Assuming a linux target, put it in your .profile

    someguy : Won't work -- see my updated question info.
  • If you're logging into a *nix box with a shell, why not put it in your shell startup?

    .bashrc or .profile in most cases.

    Ken Gentle : Fair enough - I'd go with @geocar's suggestion then.
  • You can put something like this into your shell's startup file:

    if [ -n "$SSH_CONNECTION" ]
    then
      stty erase ^H
    end
    

    The -n test will determine if SSH_CONNECTION is set which happens only when logged in via SSH.

  • Try adding the command below the end of your ~/.bashrc. It should be exited upon logoff. Do you want this command only executed when logging off a ssh session? What about local sessions, etc?

    trap 'stty erase ^H; exit 0' 0
    

    You probably could setup a .logout file from /etc/profile using this same pattern as well.

  • Put the commands in ~/.ssh/rc

    Robert Gamble : +1, I knew there had to be a better way to do this.
    Ken Gentle : +1, didn't know this existed.
