How to close firefox at a given time in linux? - linux

Question

The challenge is to be able to close firefox at a given time, to protect a person from its own "internet addiction" and ensure some rest during the night.
In this case, my partner asked to shut firefox down at 22h00, as she was staying up at night and then the next day being tired.
And when she happened to want to open firefox after 22h00, close it automatically after 15 minutes from when she opened it.
EDIT
I've written this question with an answer in place already where I created a shell script and then integrated with linux file.
There in an error on the code thatif time is before 22h00, it still is adding 15 minutes.
now=$(date +'%R')
KILL_DATE=$(date -d "22:00 today" +'%R')
if [ "$now" > "$KILL_DATE" ]; then
KILL_DATE=$(date -d "$now today + 15 minutes" +'%R')
fi
exec echo "pkill -f firefox" | at $KILL_DATE
exec $MOZ_PROGRAM "$#"

Answer 1

The solution I found for this was to:
replicate firefox file on /usr/bin/ to firefox_daytime
update the lines where firefox is loaded and use the "at" command to execute the background killing task at the specified time.
This was chosen because usually she opens firefox from the shortcuts on her "start menu".
This was only tested using openSuse.
specifically, the code for achieving this was:
now=$(date +'%R')
kill_date=$(date -d "22:00 today" +'%R')
if [ $now -gt $kill_date ]; then
kill_date=$(date -d "$now today + 15 minutes" +'%R')
fi
exec echo "pkill -f firefox" | at $kill_date
exec $MOZ_PROGRAM "$#"
Which can be found on the last lines of the new file.
/usr/bin/firefox_daytime
