Log for installed patches/softwares
 

Hi guys is there a log file in linux system where installed softwares or patches are logged?

There is no such thing as the "linux system", it will all depend on the distro you're
looking at.

if you have redhat / fedora - You might

try rpm with following switches

checklog
-qa --queryformat "%{arch}\n" check out rpm.org


let me know if you were able to find information you were looking for - I might get you exact commands :)

I have exact commands :) but just wanted you to do google :)

On RedHat variants:

man yum

and you learn:

yum list recent

Thanks for the reply guys im not actually looking for a command im just wondering if there is a certain log file in linux where i can find out if a patch or a software installation has been done :)

And again: that'll depend on the specific distro; there's no generic
patch log.

afaik - Usually its yum.log - If you are backing up that file periodiacally - you may have something.

On Debian-based systems, /var/log/dpkg.log and/or /var/log/aptitude. But, again, the answer to your question as you have asked twice is "no" because you have not specified which Linux distribution.
