<pre wrap="">Hello,
I have a little (perhaps strange) requirement:
I want to execute a script about five minutes after system boot, but only on specific weekdays (e. g. Sundays) using systemd.timer. I tried a combination of OnBootSec and OnCalendar like
OnBootSec=5m
OnCalendar=Sun
but this doesn't work.

<pre wrap="">
Well, it works but not they way you want it :) As documented, multiple
directives are additive - timer will trigger when any of them elapses.
May be it could be expressed more obviously.

There is a workaround but it's a bit more complicated than it should
be : use multiple timers.<br>
<br>
timer1.timer ; OnBootSec=5m<br>
timer1.service ; Wants=timer2<br>
<br>
timer2.timer ; Oncalendar=Sun<br>
<br>
<br>
Note that you need the intermediate unit, you cant user
Unit=timer2.timer in timer1.timer because a timer is not allowed to
start another time (I don't know why)<br>
<br>
You can also have a look at
<a class="moz-txt-link-freetext" href="https://github.com/systemd/systemd/pull/7023">https://github.com/systemd/systemd/pull/7023</a> where II suggested
something similar for upstream<br>

<pre wrap="">My script executes always after boot. I'm running systemd-228-38.1.x86_64 on SuSE LEAP 42.3. Of course, I can modify my script to ask for the current weekday, but I thought, it would be more elegant to configure it all together in the timer unit file.

This would likely require new directive or at least new syntax. Timers
define point in time, not period of time.
