Hi.

I use CentOS 5.4, the free version of RedHat. I looked in /var/log, and found some logs for "yum". Here is a script that shows a sample of when some updates were made:

Code:

#!/usr/bin/env bash

# @(#) s1	Demonstrate time of update.

echo
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1) 
set -o nounset
echo


ls -l /var/log/yum*

echo
head -3 /var/log/yum.log

exit 0

producing:

Code:

$ ./s1

(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.18-164.11.1.el5, i686
Distribution        : CentOS release 5.4 (Final)
GNU bash 3.2.25

-rw-r--r-- 1 root root 43464 Dec 23 18:33 /var/log/yum.log.1

Feb 05 11:50:50 Updated: tzdata-2009u-1.el5.noarch

I have no idea if this is always the case for an update. The files may contain more than one set of updates, so you may need to process to collect the unique dates.

Best wishes ... cheers, drl
