Emacs is there but wont run!

[aromes]

I did install my linux system with all features for emacs. But when I run "emacs"
alone, it says "bad or unrecognized command"
command as if emacs was not on my system.
At first, I though it was a matter of putting the executable of emacs in the path variable so
I can run it from whatever path.
But that was not the issue: I did a search of emacs files on my system, and found a lot of emacs related datas.
But no emacs executable under /usr/bin or /bin. The only emacs file I found and that is closed to the emacs
executable si a file called "emacsclient". But when running it, it asks for the emacs server! I tried
all of the other emacs files, but there's no emacs server or any file that did execute emacs!

How did you install emacs (via RPM, source)?
What happens when you type "which emacs"

I did install it during the linux OS intallation (simply choose
to install all emacs stuff)
