RedHat Packet Manager (rpm) helpful Linux commands with live examples !!

I would like to give some examples which can help everyone to refer the rpm command options in Linux OS.

1.     To install a package

#rpm –ivh packagename [install –i ,verbose –v , h – hash in the output]

2.  To query a package

#rpm –q packgename

#rpm –qa packagename*

#rpm –qa|grep packahe

3. Query RPM Packages in a various format using rpm –queryformat

Note: Just check the output , how it is showing the package version with release and arch details. This is very interesting and helpful command for me.

4.  Which RPM package does a file belong to? – Use rpm -qf

          

5. Locate documentation of a package that owns file using rpm -qdf

                                                                                                                                                                                       

        

6.   Information about Installed RPM Package using rpm -qi

 

7. If you have an rpm file that you would like to install, but want to know more information about it before installing, you can do the following

8.  List all the Files in a Package using rpm -qlp

Note: This is also a very useful command to know about the files in a package. I prefer to verify/check the files instead of blindly installing it.
