- _U_n_i_q 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 _s_o_r_t(1). If the --uu flag is used, just the
- lines that are not repeated in the original file are output.
- The --dd option specifies that one copy of just the repeated
- lines is to be written. The normal mode output is the union
- of the --uu and --dd mode outputs.
-
- The --cc option supersedes --uu and --dd 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
- non-space, non-tab characters separated by tabs and
- spaces from its neighbors.
-
- ++_n The first _n characters are ignored. Fields are
- skipped before characters.
