How to set the title of a tab in terminal

Both gnome-terminal in Ubuntu as well as Windows Terminal with bash allow you to set the title of the current tab you’re working in. This can be useful if you’re in multiple shell sessions and need a visual cue to switch between them.

Open up your ~/.bashrc file,

nano ~/.bashrc

And then add this function at the end:

function set-title() {
  if [[ -z "$ORIG" ]]; then
    ORIG=$PS1
  fi
  TITLE="\[\e]2;$*\a\]"
  PS1=${ORIG}${TITLE}
}

Then save and exit (Ctrl X), and reload the file with source ~/.bashrc.

Now try setting the title.

set-title Hello World!
