     Or,  depending on  your  system, use  `ps e'.   I assume the second
poster above was  on a USG system, our (4.2bsd)  ps has no f  option and
*does* have the  e option, which  is defined to print the environment of
the command.

     There is a problem with this approach; if the environment is really
big (more than about 1K for our system), ps cannot read it all.  I spent
some time grubbing about in  the sources for ps and the  kernel and this
would  NOT be easy to  fix (or if it would, someone please tell me how -
4.2bsd VAX).
