Log cutting and cleaning tool implemented in Java (source code download)

This seat has previously published an articleArticle: Log cutting and cleaning tools implemented in Java are heavily reproduced on the Network (although most of them do not indicate the source of the original article ^_^ ). There are a lot of official comments to this seat, hoping to provide toolsSource code. Therefore, this seat does not dare to copy itself, and now the sourceCodeShare it for your study and exchange.

Original article: log cutting and cleaning tools implemented in Java

 

Log cleanup is very important for routine server maintenance. If too many logs are left, disk space is seriously wasted and service performance is affected. Manual cleanup may take too much time and is difficult to meet actual requirements. For example, how do I cut a log file larger than 2 GB at every Saturday and keep the latest MB log records?

No log cutting tool can meet the requirements of this seat on the Internet, so I spent some time writing one by myself. Because it needs to be used on multiple platforms, Java is used for convenience. This tool is namedLogcutterAnd has the following features:

1. Supports all common operating systems such as Linux, Mac, and windows.
2. Supports interactive command line running.
3. Supports non-interactive running in the background (daemon process implementation in Linux/Mac, and system service implementation in Windows)
4. Two log cleanup methods are supported (delete log files or cut log files)
5. Support for gb18030, UTF-8, UTF-16LE, UTF-16BE and other common log file types cut (not cut off half a character)
6. Highly configurable (ProgramThe execution cycle, expiration time of the log file to be deleted, threshold value of the log file to be cut, and retention size can be configured.
