Translations:Limit the size of .log files & the journal/135/en
From Manjaro
Is that any file in /var/log that had log at the end of its name will be processed by the commands in the rotate.logs script. This will back up these files to a new file <name>.log.1 & empty the original file to size 0. Any previous copies with <name>.log.<number> will have their numbers bumped up one, until the day when they would have been given an 8, that is the day that they are deleted.
