+.SH "DESCRIPTION"
+.sp
+The \fBlook\fP utility displays any lines in \fIfile\fP which contain \fIstring\fP as a prefix. As \fBlook\fP performs a binary search, the lines in \fIfile\fP must be sorted (where \fBsort\fP(1) was given the same options \fB\-d\fP and/or \fB\-f\fP that \fBlook\fP is invoked with).
+.sp
+If \fIfile\fP is not specified, the file \fI/usr/share/dict/words\fP is used, only alphanumeric characters are compared and the case of alphabetic characters is ignored.
+.SH "OPTIONS"

+.sp
+\fB\-d\fP, \fB\-\-alphanum\fP
