The csh and bash config do use differnt "escape sequences"
for substitution, such as user name, host name, current
directory and "power" (root / non-root). In bash it is \,
in csh it is %.

You are right, "man bash" does list all the sequences,
as well as "man csh". For the standard prompt

	user@host:~/my/path% _

those are the corresponding codes:

Meaning		csh	bash
--------------	------	------
user		%n	\u
host		%m	\h
path		\w	%~	(includes substitution ~)
prompt sign		%#	(# for root, % for non-root)
		\$		(# for root, $ for non-root)

That's why I said csh's set prompt = "%n@%m:%~%# " equals
bash's export PS1="\u@\h:\w\$ ", because bash does have a
different default prompt (which might not be desired).

A literal % can be used for bash's PS1 setting if intended.
But it's okay to see $ for bash, and % for csh.
