       uniq - report or omit repeated lines

       uniq [OPTION]... [INPUT [OUTPUT]]

       Filter  adjacent matching lines from INPUT (or standard input), writing
       to OUTPUT (or standard output).

       With no options, matching lines are merged to the first occurrence.

       Mandatory arguments to long options are	mandatory  for	short  options

       -c, --count
	      prefix lines by the number of occurrences

       -d, --repeated
	      only print duplicate lines

       -D, --all-repeated[=delimit-method]
	      print		 all		  duplicate		 lines
	      delimit-method={none(default),prepend,separate}  Delimiting   is
	      done with blank lines.

       -f, --skip-fields=N
	      avoid comparing the first N fields

       -i, --ignore-case
	      ignore differences in case when comparing

       -s, --skip-chars=N
	      avoid comparing the first N characters

       -u, --unique
	      only print unique lines

       -z, --zero-terminated
	      end lines with 0 byte, not newline

       -w, --check-chars=N
	      compare no more than N characters in lines

       --help display this help and exit

	      output version information and exit

       A field is a run of blanks (usually spaces and/or TABs), then non-blank
       characters.  Fields are skipped before chars.

       Note: 'uniq' does not detect repeated lines unless they	are  adjacent.
       You  may want to sort the input first, or use 'sort -u' without 'uniq'.
       Also, comparisons honor the rules specified by 'LC_COLLATE'.
