Apple - Terminal Tab Title after SSH Session

Add a PROMPT_COMMAND to your .bash_profile

export PROMPT_COMMAND="echo -ne '\033]0;${USER}@${HOSTNAME}\007';$PROMPT_COMMAND"

The PROMPT_COMMAND gets executed every time the prompt is displayed.

Please note that we include the existing PROMPT_COMMAND environment variable, such that we do not lose any existing settings (i.e. update_terminal_cwd).

To make @s01ipsist's solution work with ZSH (new shell on macOS), you can add this to ~/.zshrc:

export PROMPT_COMMAND="echo -ne '\033]0;${USER}@${HOST}\007';$PROMPT_COMMAND"
precmd() { eval "$PROMPT_COMMAND" }
