whence [ -vcfpams ] name ...
       For each name, indicate how it would be interpreted
       if used as a command name.

       -v     Produce a more verbose report.

       -c     Print  the  results  in  a  csh-like format.
              This takes precedence over -v.

       -f     Causes the contents of a shell  function  to
              be displayed, which would otherwise not hap-
              pen unless the -c flag were used.

       -p     Do a path search for name even if it  is  an
              alias,  reserved  word,  shell  function  or
              builtin.

       -a     Do a search  for  all  occurrences  of  name
              throughout  the command path.  Normally only
              the first occurrence is printed.

       -m     The arguments are taken as patterns  (should
              be quoted), and the information is displayed
              for each command matching one of these  pat-
              terns.

       -s     If  a  pathname contains symlinks, print the
              symlink-free pathname as well.
