I have 2 scripts entered in pi@raspberrypi:~$ cd domoticz/scripts
free-mem.sh (28 6,23 * * * /domoticz/scripts/free-mem.sh)
domoticz_state_checker.sh (*/1 * * * * /domoticz/scripts/domoticz_state_checker.sh)
Can I run both in Crontab?
# m h dom mon dow command
28 6,23 * * * /domoticz/scripts/free-mem.sh && */1 * * * * /domoticz/scripts/domoticz_state_checker.sh
or
# m h dom mon dow command
28 6,23 * * * /domoticz/scripts/free-mem.sh & */1 * * * * /domoticz/scripts/domoticz_state_checker.sh &
or
# m h dom mon dow command
28 6,23 * * * /domoticz/scripts/free-mem.sh & */1 * * * * /domoticz/scripts/domoticz_state_checker.sh

Re: 2 scripts in Crontab
Just put in 2 lines. I suppose that it is the user crontab?
B.t.w */1 is just the same as only *

Re: 2 scripts in Crontab
Dear Eddy,
From the $ when I log on the rpi I typ:
Sudo crontab -e
From this I think there is more then one.
What is the place to put those scripts in ( now they are both in sudo crontab -e).
I googled for the right place for crontab, what is the normal path for crontab (user crontab??) ?
( /home/pi/domoticz/scripts ?)
Thanks for your time, super
Regards
Jan Bekelaar

Re: 2 scripts in Crontab
Where the crontab file resides is actually irrelevant to the user. As long as any commands mentioned in your crontab have the correct paths all will be OK. Be aware that crontab jobs do run with a rather limited environment for path variables and such. Permissions can also be an issue sometimes. If something doesn't work as sudo crontab try the same thing as your own user crontab and it might just work !

Re: 2 scripts in Crontab
Thanks philchillbill, super info,
Can you please look at the following I entered as script (bleu and green).
And the entry in crontab -e in red
Can you search for what you said "limited environment for path variables and such and permissions can also be an issue"
You said If something doesn't work as sudo crontab try the same thing as your own user crontab and it might just work.
What do you mean with that, that is way I'am confused......another crontab ??
Please a little time of you to judge what I made and maybe you can tell me how to test it.
sudo ./free-mem.sh
sudo ./domoticz_state_checker.sh
Both entered in de script dir?
Thanks in advance
from pi@raspberrypi:~$ I entered: cd domoticz/scripts and then sudo nano free-mem.sh
#!/bin/bash
free -m
sync
sudo echo 3 > /proc/sys/vm/drop_caches
free -m
from pi@raspberrypi:~$ I entered: cd domoticz/scripts and then sudo nano domoticz_state_checker.sh
#!/bin/bash
DomoticzState=`sudo service domoticz.sh status`
if [[ $DomoticzState == *"active (running)"* ]]
then
echo 'Domoticz is running. Nothing to do.'
elif [[ $DomoticzState == *"inactive (dead)"* ]]
then
echo 'Domoticz is not running. Restarting Domoticz...'
sudo service domoticz.sh restart
echo 'Domoticz restarted.'

Re: 2 scripts in Crontab
You probably need to specify a full path to where those scripts are located, so
# m h dom mon dow command
28 6,23 * * * /home/pi/domoticz/scripts/free-mem.sh
*/1 * * * * /home/pi/domoticz/scripts/domoticz_state_checker.sh
assuming your user is indeed 'pi'. You can cd into the scripts directory and do 'pwd' to see the full path name of where you are to check this.
Also, be sure to chmod +x both scripts to make sure they are executable. Then you should be good to go !
# m h dom mon dow command
28 6,23 * * * /home/pi/domoticz/scripts/free-mem.sh
*/1 * * * * /home/pi/domoticz/scripts/domoticz_state_checker.sh

Re: 2 scripts in Crontab
Dear philchillbill,
Thanks, those tips about in crontab 2 lines and that PWD command gave me the right place of the files, super!!
Indeed it was /home/pi/domoticz/scripts
Thanks again.
I have 2 small questions:
I did that chmod command.... is dooing it once after the file is made enough (when is the best moment)?
How do I know that averthing is working? Is there a command to enter when start Terminal or Putty or else?
When i go to the place of the file is (in this case) /home/pi/domoticz/scripts and type:
[pi@raspberrypi:~/domoticz/scripts$ sudo ./free-mem.sh and
sudo ./domoticz_state_checker.sh the scripts will run, but do they also when Domticz runs normal??
Regards
