RMP command not found --SOLVED--

Trying to install wedmin i can install the wget part but when typing this command after -

rmp -U webmin-1.730-1.noarch.rpm

I get an error saying "-bash: rmp: command not found

Reinstalled freepbx and still getting the same error, I’ve also tried this command:

‘yum install rpm-build’

But that fails also saying “Error: cannot retrieve repository metadata”

I have no clue about linux or commands so going with what i can find on Google.
Any help would be great.

you have a typo in rpm command
