Re: [Summary-Talk] script to gzip apache access logs on OSXS?

["Mac OS X Server Administrator" <macosxserveradmin@xxxxxxxxx>]

Thanks for the pointers, Jason,

I, too, was surprised that we couldn't find anything similar online. I
would think lots of people would want this. Is it normal for people to
be discarding their logs files weekly or monthly? I've never
understood that.

At any rate, this is what we came up with. It seems to work nicely,
leaving the current, active log file alone:



#!/bin/bash

# script to find apache logs older than X days and gzip them

# path to search
BEGINPATH=/path/to/apache/logs/
# grep pattern to search for
FILENAMEPATTERN='access\_log\.[0-9]*[^\.gzip]$'
# number of days since the file was modified, so we don't gzip active 
log file
NUMDAYS=+8

# here goes
for LOGFILE in `find $BEGINPATH -mtime $NUMDAYS | grep $FILENAMEPATTERN`
do
         # what you want the script to do
         gzip $LOGFILE
done
