Most linux commands have help built-in if you are unsure about the syntax or meaning.
's a linux guru, but I think he just copied & pasted from man rpm
can do this for yourself
The command you need to learn is man
The command you are looking for help with is rpm
So try man rpm
in a terminal. Then Page Up / Page Down and q
to quit the man pages utility and get back to the prompt.
I just tried this on my PC:
tred@vaio:~$ man rpm
No manual entry for rpm
But I do not use rpm as I have a debian-based system, which does not use rpm
is a good introduction.
Anyway, just try it.
