Last updated on MARCH 13, 2023

Goal

By default, /var/log/messages* are created with read-write permissions for 'root' user only. There might be a requirement to make the log files world readable for eg to allow an application to read and process the data in it. Changing the permissions on such files using 'chmod' might be a temporary solution as they will be recreated with the original permission during the next logrotate cron job.  This document will help understand how to set custom permissions (eg 644) on /var/log/messages permanently.
