+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility reads each
+.Ar file
+operand and searches for sequences of the form
+.Dq \&@(#)

+It prints the remainder of the string following this marker, up to
+a null character, newline, double quote, backslash, or
+.Dq \&>
+character.
+.Pp
+If the
+.Fl s
+option is specified, only the first occurrence of an identification string in
+each file is printed.
+.Sh EXIT STATUS
+The
+.Nm
+utility exits 0 if any matches were found, and 1 otherwise.
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -xpg4.2 .
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.0 .
