     The full pathname to the shell is kept in this 
     environment variable.  If it is not set when 
     the shell starts, Bash assigns to it the full 
     pathname of the current user's login shell.

You see the point is "which shell are you are 
intrested in?" Are you interested in the currently 
executing shell. Or you are interested in your 
login shell. The former is aval thru echo $SHELL.
and the error reporting. The latter is available
thru cat /etc/passwd.
