Case 01: List All Installed App Packages Using “yum”
If you want to check all installed packages in your Red Hat-based system using the yum package manager you can follow the following steps:
- At first, open the Terminal on your system.
- Now, type the following command:

If you want to check the total number of packages installed in your system then run the following command:
yum list installed | wc -lEXPLANATION- | (pipe): Pipe is used to redirect the standard output.
- wc: Count the number of lines, words, and characters.
- l: Tells the wc command to count the number of lines.
After running this the number of installed packages will be shown in your terminal like the following image:

Usually listing all installed packages in the terminal clutter the terminal. If you want to avoid that then execute the following command. It will instead list all your installed app packages’ names in a paginated manner in the ‘less’ viewer.
yum list installed | lessEXPLANATION- less: Command line pager that allows to view the text output in a paginated manner.
After executing the command the ‘less’ viewer will open with all the installed app packages listed like the previous images.

yum repoquery -a --installedEXPLANATION- repoquery: yum plugin and a command line tool that queries package information in repositories.
- a: This option specifies that I want to query from all packages in the repository.
- installed: This specifies that we want to query for installed packages.

It’s common for the terminal to become crowded when listing all installed packages. If you’d like to avoid this, simply execute the given command. The ‘less’ viewer will take care of viewing your installed app packages in a more paginated manner:
yum repoquery -a --installed | less
Upon executing the command, the “less” viewer will open, displaying a list of all the application packages shown in these previous images.
