shell or c-shell?

I forgot to say that I am using ULTRIX-32 version 3.0 and that any
other names for the shell script work in the c-shell. I am now puzzled
why the kernal can not determine correctly which shell to use if I use
that very name. Everything looks fine to me:

% ls -l ~/bin/man
-rwxr-xr-x  1 dchen         149 Mar 23 16:16 /twolf7/dchen/bin/man*
% which man
/twolf7/dchen/bin/man
% file ~/bin/man
/twolf7/dchen/bin/man:  /bin/sh script
% echo $PATH
.:/twolf7/dchen/bin:/usr/local/bin:/usr/ucb:/usr/bin:/bin:/etc:/usr/etc:/usr/new/mh


Can anyone enlighten me? Thanx.
