whence [ -vcwfpams ] 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.

       -w     For  each  name,  print `name: word' where word is one of
              alias, builtin, command, function,  hashed,  reserved  or
              none,  according  as  name  corresponds  to  an  alias, a
              built-in command, an external command, a shell  function,
              a command defined with the hash builtin, a reserved word,
              or is not recognised.  This takes precedence over -v  and
              -c.

       -f     Causes  the contents of a shell function to be displayed,
              which would otherwise not happen 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 match-
              ing one of these patterns.

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