GNU Screen – Turn Off Dynamic Window Titling for Entire Session

Make your shell change the window title every time it changes directory, or every time it displays a prompt.

For your ~/.bashrc:

if [[ "$TERM" == screen* ]]; then
  screen_set_window_title () {
    local HPWD="$PWD"
    case $HPWD in
      $HOME) HPWD="~";;
      $HOME/*) HPWD="~${HPWD#$HOME}";;
    esac
    printf '\ek%s\e\\' "$HPWD"
  }
  PROMPT_COMMAND="screen_set_window_title; $PROMPT_COMMAND"
fi

Or for your ~/.zshrc (for zsh users):

precmd () {
  local tmp='%~'
  local HPWD=${(%)tmp}
  if [[ $TERM == screen* ]]; then
    printf '\ek%s\e\\' $HPWD
  fi
}

For more information, look up under Dynamic titles in the Screen manual, or under “Titles (naming windows)” in the man page.

I see two way to do this, the first one is to make a .screenrc file by host.
Like .screenrc_serverA, .screenrc_serverB, ...
In your shell startup script set SCREENRC to something like .screenrc_`hostname`
Of course you can use the source command of screen to include something like .screenrc_default in each custom .screenrc_… files so that they only contains a caption/hardstatus line and not the whole configuration each time.

The second way would be to execute commands like screen -X hardstatus lastline ... (using if tests to execute the command with different value for ... depending of the hostname) in your shell startup script. When you will log on the server, screen -X will do nothing because screen will not yet be launched, but each time you open a new windows in screen the hardstatus will be updated.

Of course the 1st solution is better because the second one will refresh the hardstatus line each time you opened a news windows which is probably useless as the hostname will not have changed.
