I'm currently working on a multimedia machine, which I want to control via a PS4 DS4 (using ds4drv and a bit of scripting). Everything works like a charm if started via Bash / Terminal manually. But almost nothing works if started via crontab.
So far I have done some research and it seem like the error is somehow related to my environment vars.
Also ds4drv keeps crashing if it is started with the vars of cron:
hehxes@PC:~$ env - `cat ~/cronenv` /bin/sh
$ /usr/local/bin/ds4drv
[info][controller 1] Created devices /dev/input/js2 (joystick) /dev/input/event25 (evdev)

The crontab:
@reboot /usr/local/bin/ds4drv > /home/hehxes/ds4drv/verbose.log
The log show only the above output if at all.
I have already tried to specify cron's environment
@reboot /bin/bash; . /home/hehxes/.profile; /usr/bin/screen -dmS ds4drv-screen /usr/local/bin/ds4drv
but without any luck.
What am I doing wrong?
You have a semicolon after invoking bash which is incorrect. Try creating a script with the following content (let's say /home/hehxes/run_ds4drv.sh):
#!/usr/bin/env bash
. /home/hehxes/.profile
/usr/local/bin/ds4drv
Then add execute file permissions:
chmod a+x /home/hehxes/run_ds4drv.sh
And call the script in cron:
@reboot /home/hehxes/run_ds4drv.sh > /home/hehxes/ds4drv/verbose.log
