Linux Rotate Log Files

Rotating log files is a common task, and Linux systems often use log rotation tools such as logrotate for this purpose. Here’s a simple example:

1) Create a Configuration File for Logrotate:

Create a configuration file, for example, /etc/logrotate.d/myapp

/path/to/your/log/file.log {
 rotate 7              # Keep 7 rotated versions 
 daily                 # Rotate daily
 compress              # Compress rotated files
 missingok             # If the log file is missing, don't issue an error
 notifempty            # Do not rotate the log if it is empty
 create 0644 root root # Set the permissions and ownership of the new file
}

Replace /path/to/your/log/file.log with the path to your log file.

2) Run Logrotate:Logrotate is typically run by a cron job. You can force it to run manually for testing:

logrotate -vf /etc/logrotate.conf

The -v option makes logrotate run in verbose mode, so you can see what it’s doing

This is a basic example, and you can customize log rotation based on your specific needs. You can specify the rotation interval, compression, post-rotation scripts, and more in the configuration file. The configuration files for logrotate are usually in the /etc/logrotate.conf file and the /etc/logrotate.d/ directory.

Remember to adjust the paths and settings based on your system and log file locations.
