+NAME           uniq -- report repeated lines in a file
+.sp

+SYNOPSIS       uniq\b\b\b\b____ [ -ud\b\b\b___ ]  [ input [ output ] ]
+.sp
+.ti 0
+DESCRIPTION    uniq\b\b\b\b____
+reads the input
+file comparing adjacent lines.
+In the normal case, the second and succeeding copies
+of repeated lines are
+removed; the remainder is written on the output file.
+Note that repeated lines must be adjacent
+in order to be found.
+(See sort(I))
+If the -u\b\b__ flag is used,
+just the lines that are not repeated
+in the original file are output.
+The -d\b\b__ option specifies that
+one copy of just the repeated lines is to
+be written.
+Note that the normal mode output is the union of the
+-u\b\b__ and -d\b\b__ mode outputs.
+.sp
+The following example will print one copy of all
+lines in the file a\b_ that do not occur in b\b_:
