[SOLVED] crontab has no effect

Hey everone,

today I've installed Devuan for the 1st time using the devuan_daedalus_5.0.1_amd64_netinstall.iso ISO. The only selected software to install was standard system utilities and for the init system I selected openrc. It's btw the first time ever using a non systemd OS.

After the initial installation I logged in as root to install some essential packages like sudo, git, curl and make. Next I've created a file in /etc/sudoers.d for my non-root-account.

Using the non-root-account I've installed all remaining packages including my prefered window manager, spectrwm, and rebooted. Finally I've created some entries in my crontab like:

*/15 * * * * /usr/bin/mw-mailsync

Sadly non of my cronjobs will take effect so I verified that the cron daemon is running via sudo rc-service cron status resulting in:

cron is running

And a pgrep cron results in:

2116

Following cron.log using sudo tail -f /var/log/cron.log confirms that my crontab entries will be executed:

2024-05-18T11:46:01.328023+02:00 hostname CRON[14006]: (my user) CMD (/usr/bin/mw-mailsync)

I'm certainly suffering from some kind of brain fart at the moment and don't see the obvious problem, which is why I'm turning to the swarm intelligence with confidence.

Thank you for your time and effort,
dexter

Re: [SOLVED] crontab has no effect

First cabs off the rank would be:
1. Is this a PATH problem? (Non-root user typically lacks /sbin and /usr/sbin in PATH)
2. Or a problem due to that /bin/sh is dash rather than bash ?

Hmm. I've only added one entry to my $PATH. Here is the result with that extra removed (under Daedalus):

$ echo $PATH
/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

Re: [SOLVED] crontab has no effect

@ralph.ronnquist: Got it sorted and one of the reasons was the wrong syntax and, in the specific case of /usr/bin/mw-mailsync, the fact that a required script was missing. In most cases, the root of the problem can be found near the keyboard ;-) Thanks for the input, though.

@swanson: Thanks, now that I got my issues sorted I can enjoy my new environment.

The next tasks will be to install Daedalus on my remaining systems and dive deeper into the openrc sea.

Re: [SOLVED] crontab has no effect

OT: On my Devuan machines, the problems are always at the keyboard. Don't know why...
