Autorestart

cornusandu

Good morning,
I have setup in crontab to autorestart raspbian 2 times a week . Can I add a command in crontab to shut down magic mirror before restart? Pm2stop? Thank you for your help in advance

Assuming you have PM2 set up per instructions:

#       min     hour    day     Mon      wkd    command
         15      2       *       *        *      sudo reboot
         13      2       *       *        *      pm2 stop mm

not working:
46 11 * * mon,fri root pm2 stop mm
30 6 * * mon,fri root reboot
~~(With root works the reboot but not pm2 stop mm)~~
46 11 * * mon,fri pm2 stop mm ~~(also without root pm2 stop mm is not working)~~
30 6 * * mon,fri root reboot

@cornusandu create a little script

pm2 stop ?? (id or name)
shutdown -r now

but you shouldn’t have to shutdown MM manually

Fozi

For executing a reboot you need sudo privileges for the crontab. Try this

Open crontab with root privileges (sudo):
$ sudo crontab -e

Add the cronjob:
# - reboots the MM everyday at 1:05 and 13:05
# - redirects stdout and stderror to dev/null
5 1,13 * * * sudo reboot >dev/null 2>&1

Save and exit crontab.

Please note the ‚sudo‘ before ‚crontab -e’ and don‘t forget ‚sudo‘ before ‚reboot‘.

@Fozi don’t use reboot…

it is violent… use shutdown -r (restart)

to close the file system properly

Fozi

@sdetweil why violent? As far as I know reboot is an alias for shutdown -r and does exactly the same. At least that is info I found in multiple posts on stackexchange. Could you elaborate a bit on that? Just eager to understand the difference and to avoid a mistake in the future.

sdetweil

@Fozi i wasn’t aware of that… seems to me reboot always was forced hard…
so… maybe you are right…

Fozi

@sdetweil no, it‘s not a hard shutoff. You can easily check the activity on the SD card when executing reboot before it powers off. Means it stops obviously process and writes necessary data to the card first, just like shutdown.

Thank you guys. It works now. I have a secondary issue. The calendar have on top a title , I called it “my calendar” , how can I increase the font size only if the title ? The events I already increased them but the title of the module is very small
