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.
