 .Sh SYNOPSIS
 .Nm
-.Op Fl bms
-.Op Fl u
-.Op Fl BMS dir ... Fl f
-.Ar program ...
+.Op Fl p
+.Ar program
+.Op Ar program ...
 .Sh DESCRIPTION
 The
 .Nm
-utility checks the standard binary, manual page, and source
-directories for the specified programs, printing out the paths of any
-it finds.  The supplied names are first stripped of leading path name
-components, any single trailing extension added by
-.Xr gzip 1
-or
-.Xr compress 1 ,
-and the leading
-.Ql s.\&
-or trailing
-.Ql ,v
-from a source code control system.
+utility checks the standard binary directories for the specified programs,
+printing out the paths of any it finds.
 .Pp
 The default path searched is the string returned by the
 .Xr sysctl 8
 utility for the
 .Dq user.cs_path
-string, with
-.Pa /usr/libexec
-and the current user's
-.Ev $PATH
-appended.  Manual pages are searched by default along the
-.Ev $MANPATH .
-Program sources are located in a list of known standard places,
-including all the subdirectories of
-.Pa /usr/src
-and
-.Pa /usr/ports .
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl B
-Specify directories to search for binaries.  Requires the
-.Fl f
-option.
-.It Fl M
-Specify directories to search for manual pages.  Requires the
-.Fl f
-option.
-.It Fl S
-Specify directories to search for program sources.  Requires the
-.Fl f
-option.
-.It Fl b
-Search for binaries.
-.It Fl f
-Delimits the list of directories after the
-.Fl B ,
-.Fl M ,
-or
-.Fl S
-options, and indicates the beginning of the
-.Ar name
-list.
-.It Fl m
-Search for manual pages.
-.It Fl s
-Search for source directories.
-.It Fl u
-Search for
-.Dq unusual
-entries.  A file is said to be unusual if it does not have one entry
-of each requested type.
-.El
-.Sh EXAMPLES
-The following finds all utilities under
-.Pa /usr/bin
-that do not have documentation:
-.Dl whereis -m -u /usr/bin/*
+string.
+If the
+.Op Fl p
+option is specified, then the value of the environment
+variable
+.Ev PATH
+is used instead.
 .Sh SEE ALSO
-.Xr find 1 ,
-.Xr locate 1 ,
-.Xr man 1 ,
 .Xr which 1 ,
 .Xr sysctl 8
-.Sh BUGS
-The search for sources is implemented as a quick search as the
-first-level subdirectory of each element of the list of source
-directories first.  If this didn't succeed, the utility
-.Xr locate 1
-is requested to do the search in deeper nested subdirectories.  This
-might take some time, and will only succeed if the locate database is
-up-to-date.
+.Sh COMPATIBILITY
+The historic flags and arguments for the
+.Nm
+utility are no longer available in this version.
 .Sh HISTORY
 The
 .Nm
 command appeared in
 .Bx 3.0 .
-This version re-implements the historical
-functionality that was lost in
-.Bx 4.4 .
