     Name
          uniq - Reports repeated lines in a file.

     Syntax
          uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ]

     Description
          uniq reads the input file and compares adjacent lines.  In
          the normal case, the second and succeeding copies of
          repeated lines are removed; the remainder is written on the
          output file.  Input and output should always be different.
          Note that repeated lines must be adjacent in order to be
          found; see sort(C).  If the -u flag is used, just the lines
          that are not repeated in the original file are output.  The
          -d option specifies that one copy of just the repeated lines
          is to be written.  The normal mode output is the union of
          the -u and -d mode outputs.

          The -c option supersedes -u and -d and generates an output
          report in default style but with each line preceded by a
          count of the number of times it occurred.

          The n arguments specify skipping an initial portion of each
          line in the comparison:

          -n      The first n fields together with any blanks before
                  each are ignored.  A field is defined as a string of
                  nonspace, nontab characters separated by tabs and
                  spaces from its neighbors.

          +n      The first n characters are ignored.  Fields are
                  skipped before characters.
