[users@httpd] cronolog is my solution! Re: [users@httpd] Question on bin/rotatelogs

[Corp <ec...@corp.electracide.net>]

Just wanted to let others who might have the same requirements as me that
cronolog works perfectly!

CustomLog "|/path/to/cronolog /path/to/$log.%Y%m%d" custom

And it creates a new log file daily(I had to mess with dates on my test
boxes as I couldnt wait another 5 hours for it to hit midnight :) ).

Awesome.
