cronolog 介绍
灵活的日志切分的小工具
cronolog is a simple filter program that reads log file entries from
standard input and writes each entry to the output file specified by a
filename template and the current date and time. When the expanded filename
changes, the current file is closed and a new one opened. cronolog is intended
to be used in conjunction with a Web server, such as
Apache, to split the access log into daily or
monthly logs.
