## Resource Parameter Examples
|

### modules
|

|
||||
`modules` returns the information about SELinux modules as returned by [semodule -lfull](https://man7.org/linux/man-pages/man8/semodule.8.html).
|

`modules` returns information about SELinux modules using the [semodule -lfull](https://man7.org/linux/man-pages/man8/semodule.8.html) command.

Note: The `semodule -l` command does not provide `version` information in newer versions of Linux based systems like RHEL8 and Centos8 so we are not supporting that option [REF](https://access.redhat.com/solutions/2760071).
