Anacron: bash script not working

Question

hi together,
i don't know why my script isn't started by anacron - so i hope someone can help me.
bash script "update" (shortened):
#!/bin/bash
function update_notifier
yaourt -Sy > /dev/null 2>&1 && sudo -u "user" notify-send -u critical "notebook" "updates: $(yaourt -Qua | wc -l)"
case $1 in
"notifier") update_notifier;;
esac
/etc/anacrontab:
SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:
MAILTO=""
RANDOM_DELAY=30
START_HOURS_RANGE=5-22
@daily 15 cron.daily nice run-parts /etc/cron.daily
@weekly 15 cron.weekly nice run-parts /etc/cron.weekly
@monthly 15 cron.monthly nice run-parts /etc/cron.monthly
@daily 15 update.notifier /full/path/to/script/update notifier > /dev/null 2>&1
If i start my script with
update notifier
everything is working.
If i force anacron to run with
sudo anacron -f -n
everything is working.
journalctl:
anacron[2093]: Job `update.notifier' started
anacron[2093]: Job `update.notifier' terminated
PATH in anacrontab and bash are identically.
sudo -u "user" notify-send ...
gives notify-send permission to display.
So what am I missing? Thanks for any hint!

Answer 1

i've read it and understand that yaourt -Sy <package> is indeed a bad idea, but i just want to sync my database and then check for packages to upgrade. Could you give a good example with yaourt/pacman please?
so my function update_notifier should better be
sudo -u "user" notify-send -u critical "notebook" "updates: $(checkupdates | wc -l)"
right?
what is the better solution in /etc/anacrontab
@daily 15 update.notifier DISPLAY=:0 /full/path/update notifier
or something like this
@daily 15 update.notifier source /path/to/.bash_profile /full/path/update notifier
or this
@daily 15 update.notifier /bin/bash /full/path/update notifier
