You also have echo built into bash. If you type (say)
$ echo Trinity College Dublin
into bash, bash *won't* call /bin/echo, but use its own internal
variant. Try
$ type echo
$ type yum
and look at the differences.
(There seems to be an echo built into ksh, csh, the Bourne shell, and
most derivatives.)
And, on Fedora, try
$ echo --version
$ /bin/echo --version.
tcsh's echo has its own oddities depending on how echo_style is set.
I'm sorry if I'm shattering some of your illusions here. But there is a
lot of Unix precedent for things that do *much* the same thing to be
called by the same name.
