Detailed Explanation

Controlling the sizes of log files on a Linux server is crucial due to their continuous growth. As log files accumulate, they can consume valuable storage space, server resources, and cause performance issues. To address this problem, log rotation is commonly employed in most Linux distributions.

$ logrotate --version
logrotate 3.19.0
    Default mail command:       /usr/bin/mail
    Default compress command:   /bin/gzip
    Default uncompress command: /bin/gunzip
    Default compress extension: .gz
    Default state file path:    /var/lib/logrotate/status
    ACL support:                yes
    SELinux support:            yes

<syntaxhighlight lang="bash"> The main Logrotate configuration $cat /etc/logrotate.conf

1. see "man logrotate" for details
2. global options do not affect preceding include directives
3. rotate log files weekly, the frequency of log rotation. Alternatively, you can specify another time interval (hourly, daily, monthly, or yearly).

weekly

1. use the adm group by default, since this is the owning group
2. of /var/log/syslog.
