SOLUTION: There was a bug in the program. Instructions below with sleep helped me find it.

Does anyone know how to do this?

I tried the following, but the backslash escape before a space did not work as expected with xterm or Apple Terminal:

 SEARCH=' ' REPLACE='_' # XXX fix display of spaces PWD_SPACE="${PWD//$SEARCH/$REPLACE}"

Full context:

 # replace spaces with percent sign for pathnames # with spaces SEARCH=' ' REPLACE='%20' PWD_URL="${PWD//$SEARCH/$REPLACE}" SEARCH=' ' REPLACE='_' # XXX fix display of spaces PWD_SPACE="${PWD//$SEARCH/$REPLACE}" if [ -n "$KSH_VERSION" ]; then TMP_PWD=$(shortpath $PWD_SPACE) else TMP_PWD=$(shortpath_bash_trunc $PWD_SPACE) fi if [ -t 0 ]; then if [ "$TERM_PROGRAM" == "Apple_Terminal" ]; then #titlebar "${SYS} : ${PWD##*/}" $ECHOE "\033]0;\007" $ECHOE "\033]6;\007" $ECHOE "\033]7;file:$PWD_URL\007" elif [[ "$TERM" == *"xterm"* ]]; then $ECHOE "\033]0;$TMP_PWD\007" $ECHOE "\033]6;\007" $ECHOE "\033]7;\007" fi fi

    xterm has no problems with spaces in titles, and has no need to change spaces into %20. Do you see the correct results with printf '\033]0;%s\007' "$PWD"' ; sleep 30 - at least for 30 seconds? Commented Oct 28, 2019 at 6:10
  • why the sleep? would that not delay the entire shell read, eval, print loop? Commented Oct 28, 2019 at 14:14

    The point of the sleep is to stop either PS1 or PROMPT_COMMAND or something like them changing the title again immediately after the printf has set it, leading you to think it hadn't worked. Yes I tested it for an xterm. Commented Oct 28, 2019 at 16:58
