Change iTerm2 window and tab titles in zsh

I want to label the window tabs of terminal sessions. I'm using the zshell in iterm2 on OSX. Is it possible to change the label of a window tab dynamically in the terminal?

Solution 1:

You can enter the following in zsh to set the window title of iTerm2:

echo -ne "\e]1;this is the title\a"

If you want to automate that to insert e.g. the current time or working directory, edit your zsh configuration files to set the title in the precmd() function to e.g. $PWD.

echo -ne "\e]1;$PWD\a"

You can read about the precmd function in man zshmisc in the section SPECIAL FUNCTIONS.

Solution 2:

What works for me:

echo -e "\033];this is the title\007"

If you use Mac OSX and iTerm, iTerm2::

• iTerm → Preferences → Appearance → Window & Tab Titles → uncheck all

If you use Oh My Zsh, then you may need to edit your settings. Your settings are typically in the file ~/.zshrc. You want to add or edit your settings to make sure this line exists:

DISABLE_AUTO_TITLE="true"

Solution 3:

One of the amenities of using iTerm is the possibility of setting window title & tab title separately:

# $1 = type; 0 - both, 1 - tab, 2 - title
# rest = text
setTerminalText () {
    # echo works in bash & zsh
    local mode=$1 ; shift
    echo -ne "\033]$mode;$@\007"
}
stt_both  () { setTerminalText 0 $@; }
stt_tab   () { setTerminalText 1 $@; }
stt_title () { setTerminalText 2 $@; }

This way you can immediately see what host you're connected to in what window, and the window title for each tab shows user & CWD.

Solution 4:

A precmd does the trick. However, some oh-my-zsh themes mess around with the window title. Set PR_TITLEBAR to an empty string to fix it.

set-window-title() {
  # /Users/clessg/projects/dotfiles -> ~/p/dotfiles
  window_title="\e]0;${${PWD/#"$HOME"/~}/projects/p}\a"
  echo -ne "$window_title"
}

PR_TITLEBAR=''
set-window-title
add-zsh-hook precmd set-window-title

I would also recommend playing around with the tab settings of iTerm2 in Preferences -> Appearance.
