NAME

SYNOPSIS


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

 

DESCRIPTION






       Discard  all but one of successive identical lines from INPUT (or stan-
       dard input), writing to OUTPUT (or standard output).

       Mandatory arguments to long options are  mandatory  for  short  options
       too.

       -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

       --version
              output version information and exit

       A field is a run of whitespace, then non-whitespace 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'.
