Those little "details" were left as an excercise for the user.

I guess since you one-up'd me I'd better try the same.  :)

How about

   #!/bin/sh
   today=`/usr/bin/date +"%Y-%m-%d"`
   cd /data/logs/www
   for file in *_log ; do > /dev/null 2>&1
       mv -f $file $file.$today
       gzip $file.$today
   done
   /usr/local/apache/bin/apachectl graceful

This is pretty much what we do.  It renames and compresses all "_log" files
(we use OpenSSL and a few other custom things that write files with names
like that).  Just quick note to those that may attempt this.  Restarting the
webserver is a must.  Unix machines are fairly smart.  If you simply move
the file, the OS knows that and will continue to log to that newly named
file.  Stopping or restarting the web server will flush data to the file,
close it, then reopen a new one.

I actually just changed my cron jobs this week to use the graceful option
(we replaced our Alpha with a Sun, so I had to tweak everything).  I don't
know how long it's been there.
