The command 'env' will list all initialized shell variables in both bash and 
the standard shell.  The command 'set' will list all initialized shell 
variables in bash, csh, DOS, and COMMAND.COM.

There is no known command to list uninitialized variables, since that list is 
infinite.

If you issue the command "set -u" you will get barf if you try to reference an 
uninitialized shell variable.  A shell variable initialized to an empty 
string is not the same thing as an uninitialized shell variable.
