How to change Terminator title terminal title, ZSH on Debian?

You set your window title with the xtem escape sequences, in most implementations the first will work best:

echo -en "\e]0;string\a" #-- Set icon name and window title to string
echo -en "\e]1;string\a" #-- Set icon name to string
echo -en "\e]2;string\a" #-- Set window title to string

EDIT: The above only sets the title once. To set zsh to always display the sting in the title you add the following to your .zprofile in your home directory:

case $TERM in
    xterm*)
        precmd () {print -Pn "\e]0;string\a"}
        ;;
esac

The following worked for me to rename each tab in gnome-terminal. I added the following code to my ~/.zshrc file.

precmd () { print -Pn "\e]0;$TITLE\a" }
title() { export TITLE="$*" }

This creates a title function to rename each tab.

Note, if you are using oh-my-zsh you will need to disable its auto title command. You can do that by uncommenting this line in your ~/.zshrc file:

DISABLE_AUTO_TITLE="true"

This should work regardless of the shell used:

printf "\033];%s\07\n" "hello world"

Earlier answers didn't quite work for me. Not without some hiccups (not always refreshed or something). It may be due to the fact I had ZSH, without oh-my-zsh. Fortunately I learned of chpwd, so:

chpwd() {
  [[ -t 1 ]] || return
  case $TERM in
    sun-cmd) print -Pn "\e]l%~\e\\"
      ;;
    *xterm*|rxvt|(dt|k|E)term) print -Pn "\e]2;%~\a"
      ;;
  esac
}

1. chpwd gets called every time directory is changed.
2. first time you launch xterm (or others) this doesn't count as directory change, so put chpwd call directly in .zshrc

As I do not use oh-my-zsh, I don't know if it works there, but unless they've changed and overwritten chpwd (in which case you will be overwriting their overwrite :D), it should.
