First, no problem with being blunt; it facilitates communication. :-) That said, we're not keeping the files for particularly long, so "archival" isn't an issue for us. It's merely that the files are extremely compressible (compressed size is about 12% the original), but for various reasons outside the control of those of us who run the machines, we need to keep some number of the most recent of them uncompressed. > I'd rather see an extension for newsyslog which would rotate foo to > foo.2007-08-12.gz, iff rotation is done every day at midnight. >=20 > That way, you get a 'stable' name, which makes it easier to find the > logfile for 1999-12-31 or 2000-01-01 some years from now. And on the other hand, to find the log for 3 days ago, you need to have a better idea of the current date than I generally do unless I check (either my watch or `date`). :-} So there are trade-offs. :-} Then again, I'm rather in the habit of using "ls -ltr ...." when I'm interested in the more recent of a set of files. > Right now, I have to use syslog-ng for that purpose. Well, I certainly wouldn't object to the existence of such a feature, whether or not I'd use it myself. :-) Peace, david --=20 David H.
