Linux Shell Scripting Cookbook - Third Edition

How to do it...

The system's logrotate configuration files are held in /etc/logrotate.d. Most Linux distributions have many files in this folder.

We can create a custom configuration for a log file (say /var/log/program.log):

$ cat /etc/logrotate.d/program 
/var/log/program.log { 
missingok 
notifempty 
size 30k 
  compress 
weekly 
  rotate 5 
create 0600 root root 
} 

This is a complete configuration. The /var/log/program.log string specifies the log file path. Logrotate will archive old logs in the same directory.
