We agree so far.

you probably meant "searches along the PATH variable", no? In both cases, if found, the executable
wind is run and the shell exits (or not exits) depending on the return code of this program.
And, yes, the best thing one can do with the
csh is to forget it ever existed.
I hope this helps.

CD(1) BSD General Commands Manual CD(1)
NAME
cd -- change working directory
SYNOPSIS
cd directory
DESCRIPTION
Directory is an absolute or relative pathname which becomes the new working directory. The interpretation of a relative pathname by cd
depends on the CDPATH environment variable (see below).
ENVIRONMENT
The following environment variables affect the execution of cd:
CDPATH If the directory operand does not begin with a slash (/) character, and the first component is not dot (.) or dot-dot (..), cd
searches for the directory relative to each directory named in the CDPATH variable, in the order listed. The new working directory
is set to the first matching directory found. An empty string in place of a directory pathname represents the current directory. If
the new working directory was derived from CDPATH, it will be printed to the standard output.
HOME If cd is invoked without arguments and the HOME environment variable exists and contains a directory name, that directory becomes the
new working directory.
See csh(1) for more information on environment variables.
The cd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
csh(1), pwd(1), sh(1), chdir(2)
STANDARDS
The cd command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
