A question about RPM : is this software installed after all?

[julianLiu]

Hi,

My platform is fc8 X86_64. I'm going to install p7zip, so I downloaded a rpm for it, the file name was ``p7zip-4.51-3.fc8.x86_64.rpm''. I used the command
---
#rpm -ivh p7zip-4.51-3.fc8.x86_64.rpm
Preparing... ########################################### [100%]
package p7zip-4.51-3.fc8 is already installed

===
to install it, and as you see, the system said it was installed. But, when I verified if it is really installed, as shown below, the system said that it was not installed.
---
# rpm -q p7zip-4.51-3.fc8.x86_64.rpm
package p7zip-4.51-3.fc8.x86_64.rpm is not installed
===

Can any one tell me what is happening?

thanks in adv.

HI julianLiu, Welcome to LinuxForums.
Try using just the package name when querying rpm packages.
rpm -q p7zip

Once you have installed an rpm package, you simply use the name of the package for most operations and omit the "rpm" extension. You can also omit version numbers, except for kernels (specifically if you have multiple kernels installed).
