A previous post used info that is out of date for Ubuntu Mate 18.04.

NOT a duplicate.

According to this info


I have this script in /lib/systemd/system-sleep/

# located in /lib/systemd/system-sleep/
# Created 4/2/19
exec 2> /tmp/systemd_suspend_test_err.txt
if [ "${1}" = "pre" ]; then
  # Do the thing you want before suspend here
  echo "we are suspending." > /tmp/systemd_suspend_test.txt
elif [ "${1}" = "post" ]; then
  # Do the thing you want after resume here
  echo "and we are back from being suspended" >> /tmp/systemd_suspend_test.txt

None of the echo statements work.


I feel kind of stupid, but I forgot to set the execute bit.

Now the script works.

I used chmod +x

  • Can you please add the command that you used to 'set the execute bit'? – earthmeLon Apr 2 '19 at 23:31
