I need to find out all the latest patches on my Linux server

[Jorge Cocomess]

Greetings,

I need to know what would be the command to use to find out what are some of the patches I've loaded into the Linux server? I am currently running RHAS 2.1 server.

Thank you in advance.

Jorge

# rpm -qa

this should list all installed rpms.

If you've set up 'up2date' correctly, you can also use 'up2date -l' to list the patches that are available to the server.

Also, if you have a Red Hat Network login for the server, you can log into their service via a web browser ( https://rhn.redhat.com ), then click on the associated server under Systems.

in linux there are not really 'patches' as you would have in hpux/solaris/windows, but it's rather updates of packages.

meaning, there is not really a command that will show you 'just patches', because each 'patch' commes as a complete new updated package.

you can do it as followed. after install of the system is finished you dump your current rpm database for ex. rpm -qa > rpm.0.list

next time you run - rpm -qa > rpm.1.list

then you can 'diff' between the 2 files to find out the differences.
