queriying installed softwares

angos · 03-31-2011, 04:52 AM

hi all
i have been reading some linux docs on how to query install softwares.
rpm -q oracle,
but i am working on a server that i know that has oracle in it,
but the rpm -q oracle command doesnt show that it has oracle in it.
is there any other command to check for installed softwares in linux?

Please tell which distribution you use so we can tell you what is the relevant command in your case.

Not all distributions use rpm to install or query software.

am using redhat release 4

Then rpm should be the command to use, as it stands for 'Red Hat Package Manager'

May be try 'rpm --rebuilddb' then before 'rmp -q', see 'man rpm'.

To list all packages currently installed

Code:

rpm -qa

To find packages with oracle in the name

Code:

$ rpm -qa | grep -i oracle

To find information about a specific package

Code:

$ rpm -qi packagename

As Didier Spaier said, 'man rpm' for more information.
