UNIQ(1)                       User Commands                      UNIQ(1)

НАЗВАНИЕ

       uniq - report or omit repeated lines

СИНТАКСИС

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

ОПИСАНИЕ

       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 too.

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

       -d, --repeated
              only print duplicate lines, one for each group

       -D     print all duplicate lines

       --all-repeated[=METHOD]
              like -D, but allow separating groups with an empty line;
              METHOD={none(default),prepend,separate}

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

       --group[=METHOD]
              show all items, separating groups with an empty line;
              METHOD={separate(default),prepend,append,both}

       -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
              line delimiter is NUL, 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 blanks (usually spaces and/or TABs), then
       non-blank characters.  Fields are skipped before chars.

       'uniq' does not detect repeated lines unless they are adjacent.
       You may want to sort the input first, or use 'sort -u' without
       'uniq'.
