I didn't know it all, but I do know that /etc/logrotate.conf and /etc/logrotate.d control, well, log rotation.
ISTR that "In the old days" syslogd would use 2 criteria to decide whether to rotate the log - size of file and how long it had been since last rotation. I don't remember all the rules (like, if the file is zero length, does the rotation happen anyway, or not), but do remember that you could get a log rotated either because of size OR time. A perusal of /etc/logrotate.d/* will reveal a lot of interesting stuff... (Along with a man page perusal J) Notice that there are nifty 'commands' like 'rotate 10' and 'weekly' which tell syslogd to keep 10 <unit of rotation time>'s copies of the logs ('rotate 10'), and rotate the log files once per week ('weekly'), regardless of size. There are others, like 'compress' (to compress them), and 'delaycompress' which apparently does not compress the 2 most recent backup log files. So, this means that somewhere in the configuration you should find 'daily', 'compress', 'delaycompress', and 'rotate 8' being applied to /var/log/syslog. On a slightly different topic, I have found that some versions of 'less' will automatically decompress compressed files to text. Or at least, one time I mistakenly said 'less /var/log/syslog*' when some of them were zipped, and LO! I didn't see any binary junk - it decompressed them for me. YMMV!

From my inspection of the log it seems as if it covers a little more than a day. Teach mw about this! I'm all ears! On Tue, May 8, 2012 at 10:26 PM, Michael Havens < > wrote: you guys are so helpful. Well, there is a /var/log/syslog and syslog.1 but after that it is syslog.2-7.gz, not 'z'. Does that sound right? Which is the most recent?
