DLDUPL (DELETE_DUPLICATE_LINES) -- Strip repeated lines from a file.
usage:  DLDUPL [-C] [pathname ...]


FORMAT

  DLDUPL [-C] [pathname ...]


  DLDUPL reads the input file(s), comparing adjacent lines.  Second and
  succeeding copies of repeated lines are removed; the remaining lines are
  written to standard output.


ARGUMENTS

  pathname
  (optional)       Specify input file.  Multiple file names permitted;
                   separate names with blanks.
                   Default if omitted: read standard input


OPTION

  -C               Write number of occurrences of each line to standard output.


EXAMPLE

  Suppose you have two dictionary files.  To create one dictionary file
  containing the words from both, use:

        $ srf -m dict1 dict2 | dldupl >dict.new

  This merges the words from the two files (SRF -M), then deletes any duplicate
  words and saves the result in the new dictionary.
