OK....
I have had problems in the past with crontab parsing a command. Would I use:
@reboot root echo none | tee /sys/class/leds/blue\:heartbeat/trigger
?
Or do I have to make a script and run that?
Since this is a crontab, you can use normal shell redirection:
@reboot root echo none > /sys/class/leds/blue\:heartbeat/trigger
in a file in /etc/cron.d/
The 'echo foo | sudo tee' thing is what you do for people who are
using sudo to echo output into a file -- so often people think they
can do 'sudo echo none > /some/path' and will be surprised it doesn't
work.
Thanks. This is my first encounter with 'tee'. I guess because I
rarely use sudo, and work in su if I need to do root things.
I still think it makes sense to create it as a systemd unit.
Seems the better, long-term way to go, but right now I don't have time
to learn enough about making systemd unit files.
Thanks
