set terminal title in Ubuntu

The option to set the terminal title has been deprecated in 16.04 LTS, however there is still a way to set the title. Edit your ~/.bashrc file and add the following lines:

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

After that close and reopen the terminal or source your .bashrc (command: source ~/.bashrc) and you can set the title by simply typing:

set-title "<title>"
