 .SH DESCRIPTION
 .SS "/usr/bin/cd"
-.sp
-.LP
 The \fB/usr/bin/cd\fR utility changes the current directory in the context of
 the \fBcd\fR utility only. This is in contrast to the version built into the
 shell. \fB/usr/bin/cd\fR has no effect on the invoking process but can be used
 to determine whether or not a given directory can be set as the current
 directory.
-.SS "sh"
-.sp
-.LP
-The Bourne shell built-in \fBcd\fR changes the current directory to
-\fIargument\fR. The shell parameter \fBHOME\fR is the default \fIargument\fR.
-The shell parameter \fBCDPATH\fR defines the search path for the directory
-containing \fIargument\fR. Alternative directory names are separated by a colon
-(\fB:\fR). The default path is \fB<null>\fR (specifying the current directory).
-The current directory is specified by a null path name, which can appear
-immediately after the equal sign or between the colon delimiters anywhere else
-in the path list. If \fIargument\fR begins with `\fB/\fR', `\fB\&.\fR', or
-`\fB\&.\|.\fR', the search path is not used. Otherwise, each directory in the
-path is searched for \fIargument\fR. \fBcd\fR must have execute (search)
-permission in \fIargument\fR. Because a new process is created to execute each
-command, \fBcd\fR would be ineffective if it were written as a normal command;
-therefore, it is recognized by and is internal to the shell. (See \fBpwd\fR(1),
-\fBsh\fR(1), and \fBchdir\fR(2)).

-\fBchdir\fR is just another way to call \fBcd\fR.
 .SS "csh"

 If \fIdir\fR is not specified, the C shell built-in \fBcd\fR uses the value of
 shell parameter \fBHOME\fR as the new working directory. If \fIdir\fR specifies
 a complete path starting with `\fB/\fR', `\fB\&.\fR', or `\fB\&.\|.\fR',
 \fIdir\fR becomes the new working directory. If neither case applies, \fBcd\fR
 tries to find the designated directory relative to one of the paths specified
