Here is the command which list all the installed rpm software packages..

rpm -qa
  1. Above command list all packages, q means query and a means all.
  2.  
  3. rpm command generally used for installing rpm archive packages manually, and one can also see all installed packages as mentioned.
  4.  
  5. If you want to see few installed packages at a time then use below command
  6. <pre lang="bash">rpm -qa | less

This command lists the installed rpm packages in less linux shell text editor, it will show few at a time, to see more just keep pressing enter button on your keyboard.

To see specific rpm software package like mysql or python, run below command

rpm -qa | grep mysql -- To see mysql packages
  1. rpm -qa | grep python -- To see python packages

To list the rpm packages in sorted manner, run below command

rpm -qa | sort | less
  1. To get sorted rpm packages list in text file, run below command
  2. <pre lang="bash">rpm -qa | sort &gt; packages.txt

I hope these commands may help in finding installed rpm packages. For any help email me or give a comment below in the comment box.
