UNIQ(1)                                                   UNIQ(1)

     NAME
          uniq - report repeated lines in a file

     SYNOPSIS
          uniq [ -ud ] [ file ]

     DESCRIPTION
          Uniq copies the input file, or the standard input, to the
          standard output, comparing adjacent lines.  In the normal
          case, the second and succeeding copies of repeated lines are
          removed.  Repeated lines must be adjacent in order to be
          found.

          -u   Print unique lines.

          -d   Print (one copy of) duplicated lines.
