How can I satisfy both the need to remove yesterday's log file while keeping the current day?
Hi,
I perfectly understand your problem. "copytruncate" is not your friend here so, taking "copytruncate" out of the picture, I really don't see a quick fix as logrotate doesn't provide a facility to work on files OLDER than X days. If there was such an option, you could tell it to rotate all the *.log files from the previous day (move them & compress, not copy them) without affecting your current day log.
Possible workarounds:
1) Modify your app if you can so that it stops creating new files daily. Something like app.log.
Use the "copytruncate" & "dateext" (along with your other options) in the logrotate configuration so that every day the file is COPIED & COMPRESSED to app.log.20111119.gz. That way your file is truncated everyday and you'll have nicely compressed historical archives (with the date appended) which you can keep for X days depending on your "rotate X" value.
2) get creative with the "prerotate" and "postrate" options of logrotate.
3) if your app is smart enough to create a log daily perhaps you could tell it to compress the previous file and get rid of logrotate for that.
