command name.
If the @option{-t} option is used, @code{type} prints a single word
which is one of @samp{alias}, @samp{function}, @samp{builtin},
@samp{file} or @samp{keyword},
if @var{name} is an alias, shell function, shell builtin,
disk file, or shell reserved word, respectively.
which is one of @samp{alias}, @samp{keyword}, @samp{function},
@samp{builtin}, or @samp{file},
if @var{name} is an alias, shell reserved word, shell function,
shell builtin, or executable disk file, respectively.
If the @var{name} is not found, then nothing is printed, and
@code{type} returns a failure status.
If the @option{-p} option is used, @code{type} either returns the name
of the disk file that would be executed, or nothing if @option{-t}
would not return @samp{file}.
of the executable file that would be found by searching @code{$PATH},
or nothing if @option{-t} would not return @samp{file}.
The @option{-P} option forces a path search for each @var{name}, even if
@option{-t} would not return @samp{file}.
If a command is hashed, @option{-p} and @option{-P} print the hashed value,
which is not necessarily the file that appears first in @code{$PATH}.
If a @var{name} is present in the table of hashed commands,
options @option{-p} and @option{-P} print the hashed value, which is not
necessarily the file that appears first in @code{$PATH}.
If the @option{-a} option is used, @code{type} returns all of the places
that contain an executable named @var{file}.
This includes aliases and functions, if and only if the @option{-p} option
is not also used.
that contain a command named @var{name}.
This includes aliases, reserved words, functions, and builtins,
but the path search options (@option{-p} and @option{-P}) can be supplied
to restrict the output to executable files.
If @option{-a} is supplied with @option{-p}, @code{type} does not look
in the table of hashed commands, and only performs a @code{PATH}
search for @var{name}.
If the @option{-f} option is used, @code{type} does not attempt to find
shell functions, as with the @code{command} builtin.
