SSH muddles the title

Normally, the macOS title bar includes the current directory name. When you connect to a remote host with openssh on macOS, the title bar gets updated to be “$(whoami)@$(hostname): $(pwd)” instead. Unfortunately when you exit ssh, the terminal title bar is not restored and continues to say you are on a remote host.

Once you see it, you can’t unsee it.

I’m sorry.

My solution is to use arcane escape sequences to reset the Terminal title every time bash generates a new prompt:

# Add to ~/.bashrc
# force reset of the current directory name in terminal title
# to reset it after SSH sessions end.
PROMPT_COMMAND='echo -ne "\033]0;$(basename ${PWD})\007"'

The incantation is slightly different but conceptually the same for zsh.

# Add to ~/.zshrc
function clear_term_title {
# removes the text that ssh puts into the terminal title
printf '\033]0;\007'
PROMPT="$(clear_term_title)%% "
