How can I uninstall software in CentOS or Redhat Linux?

To uninstall software in CentOS or Red Hat Enterprise Linux (RHEL), you can use the rpm command with the -e option.

For example, to uninstall a package called package-name, you can use the following command:

$ sudo rpm -e package-name

This will remove the package, but it will leave behind any configuration files that were created when the package was installed.

You can also use the yum command to remove packages in CentOS or RHEL. The yum command is a front-end to the rpm command, and it provides additional functionality for managing packages.

To remove a package with yum, you can use the erase subcommand. For example:

$ sudo yum erase package-name

This will remove the package, but it will leave behind any configuration files that were created when the package was installed.

You can also use the dnf command to remove packages in CentOS or RHEL. The dnf command is a newer package manager that is used in place of yum in some newer versions of CentOS and RHEL.

To remove a package with dnf, you can use the erase subcommand. For example:

$ sudo dnf erase package-name

This will remove the package, but it will leave behind any configuration files that were created when the package was installed.

Here are some additional ways to uninstall software in CentOS or Red Hat Enterprise Linux (RHEL):

  1. You can use the rpm command with the -e option and the --nodeps option to remove a package even if it has dependencies on other packages. For example:
$ sudo rpm -e --nodeps package-name

This can be useful if you want to remove a package that is causing problems and you don’t care about preserving the dependencies of that package. However, be aware that removing a package with dependencies can cause other issues on your system, so use this option with caution.

  1. You can use the yum command with the autoremove subcommand to remove packages that were automatically installed to satisfy dependencies for other packages and are no longer needed. For example:
$ sudo yum autoremove

This will remove all automatically installed packages that are no longer needed.
