Update: October 16, 2019.
Thanks to gnome expert's answer on linked question below, a faster more stable method of relaunching Nautilus File Manager has been implemented.
This turned out to be a challenging problem because Nautilus is always running to control the desktop. If you kill the program
nautilus all your desktop icons will disappear. When nautilus is running and your desktop icons are present and you type
nautilus in the terminal then the Nautilus File Manager appears.
Copy this script to a file called
# NAME: ttlus (Twenty Thousand Loops Under Startup)
# PATH: $HOME/askubuntu/
# DESC: Answer for: https://askubuntu.com/questions/1180043/how-can-i-automatically-relaunch-nautilus-if-i-quit-the-program
# Call Nautilus, named after Twenty Thousand Leagues Under the Sea novel,
# 20,000 times in loop from Startup Applications
# DATE: October 10, 2019. Modified October 16, 2019.
# NOTE: Things that don't work:
# UPDT: Rpelace loop with occassional focus grabbing and unpredictable delays:
# while ps -L -p "$PID" -o pid,nice,lwp,comm | grep pool > /dev/null ; do
# while gdbus introspect --session --dest org.gnome.Nautilus \ ... 3 lines
if [[ $PID == "" ]] ; then
notify-send "ERROR in $0: Cannot find nautilus PID"
for (( l=0; l<LoopLimit; l++ )) ; do
# Is nautilus file manager running? 1 Window only is desktop icons
while gdbus introspect --session --dest org.gnome.Nautilus \
--object-path /org/gnome/Nautilus --recurse | \
grep -q '^ *node /org/gnome/Nautilus/window/' | \
grep -v '/window/1' ; do
"$Program" "$HOME" 2> /dev/null
sleep $(( Sec / 2 ))
notify-send "ERROR in $0: $Program exceeded $LoopLimit loop limit"
Make it executable with
chmod a+x ~/ttlus
First test is by typing
~/ttlus & in the terminal. After you are satisfied add it in Startup Applications.
If program runs amok use:
$ pgrep ttlus
$ kill 7970
+ Terminated ttlus
- Due to the
sleep "$Sec" command after exiting Nautilus with Alt+F4 or clicking X on window a three second delay (to reduce resource usage) will occur before Nautilus reappears on the desktop.
