Audit all your docker-compose.yml files

If you would like to check if the timezones are correctly setup in all your docker.compose.yml files or just want to list all values of a certain property (subnet, PUID, PGID, ...)
Replace TZ= by the property name you would like to audit.

sudo find . -type f -name "docker-compose.yml" -exec grep -H "TZ=" {} \;
