I cannot believe in the file > date for this. In my bourne shell version, I say 'daily' 'weekly' 'monthly' and calculate the number of days to keep the logs, based on find(1) and mtime. In a perl version, it walks the directory looking for similarly named files, and stat(2)s them, looking for files X seconds old, X being calculated from the number of seconds in a day, and the number of days to keep the files. > Also, strftime needs a date as an argument.

(This does not mean I've changed my mind about > newsyslog and logrotate needing to be fully rewritten) I think it should be possible to specify the number of days/weeks/months to keep files. Of course, since the .0, .1 rotation method is used so much, it logrotate should be able to handle that, too. How does that sound?
