Job Scheduler problem

#1 Post by jeffreyC »

After noticing that one of the two conkies I have running on my MX-21 desktop was filling up my RAM as time passed I thought to set up a scheduled job of running the conky start script at midnight.
The part where it killed the running conkies ran, but it did not start the conkies, the same script works when started manually via Thunar Custom action.
My QSI:

It probably has to do with the environment being different when running in cron as when running from Thunar - but without seeing the script we can't really tell you.

conky-startup.sh

Code: Select all

#!/bin/sh

sleep 6s
killall -u $(id -nu) conky 2>/dev/null
cd "$HOME/.conky"
conky -q -c "$HOME/.conky/BL-Cal-mod3.conkyrc" &
cd "$HOME/.conky/MX-MyConky"
conky -q -c "$HOME/.conky/MX-MyConky/MySysInfoConky" &
exit 0
located in my .conky folder.

I'm assuming you used the Job Scheduler applet to set this up. Check if the job is set to run as root or your username.
If run as root $HOME = /root (and id -nu won't be what you expect either) and the job will fail.

I set the job to run as my username using the Job Scheduler applet.
It ran the killall conky part and quit.

cron executes scripts in the background inside of a limited environment.

I believe you'll need to give some environment variables, like "DISPLAY" at minimum.

I was logging in to say exactly this. I find that running "env DISPLAY=:0.0 ~/.conky/conky_startup.sh" or however I instantiate it always seems to work when I'm starting conky from, say, inside of a tmux terminal session that normally wouldn't start it correctly.

I'll also add that my crontabs usually benefit from adding a PATH variable, and a MAILTO variable if I want to collect error messages.
