# Purpose {{{
## Create a temp file (to monitor) if an upgrade is available for AdGuard Home
## project on Github.
## It's based on the AdGuard Home bin path to get the current version.
## How-to use {{{
### 1. Needs releasetags script, in the same directory
### cf. https://git.101010.fr/gardouille-dotfiles/scripts/github/releasetags
# wget https://git.101010.fr/gardouille-dotfiles/scripts/raw/branch/master/github/releasetags
### 2. Create a cron job with AdGuard Home binary's path as first argument, eg.
#00 20 * * * root /opt/repos/ipr.scripts/github/check_adguard_update --bin /opt/adguard/AdGuardHome/AdGuardHome
### 3. Monitor the temp file: /tmp/.adguard.upgrade
# Or enable MAILTO in cronjob and edit the script to print a message.
# Or send a mail.
# …
