I sometimes want to start emacs with a shell, but I also want to
rename the default name '*shell*'.
I have:
    emacs -title ${TITLE} --eval '(shell) (rename-buffer "shell")'

But the buffername is not renamed.
In *Messages* I see:
    (emacs --eval (shell) (rename-buffer "shell"))

And not an error or a warning.
If I do 'M-:' and then '(rename-buffer "shell")' the buffer is
renamed.

What am I doing wrong?

I found a way:
     emacs -title ${TITLE} --eval '(shell "shell")'

The only problem with this is that both the '*scratch*' and the
'shell' buffer are displayed. Not a big problem, but is it possible to
have only the 'shell' buffer displayed?

Because shell calls pop-to-buffer, whose doc string says:

Select buffer buffer in some window, preferably a different one.
...
If `pop-up-windows' is non-nil, windows can be split to do this.

Try:

emacs -title ${TITLE} --eval '(let ((pop-up-windows nil)) (shell "shell"))'

I found a way around my problem, but I am still interested why the
first way does not work. ;-}

The --eval command line option calls the eval function, which takes
exactly 1 argument (a lisp form).
