DESCRIPTION

OPTIONS

-D, --all-repeated=delimit-method

print all duplicate lines. Delimiting is done with blank lines. [default: none]

[possible values: none, prepend, separate]

--group=group-method

[possible values: separate, prepend, append, both]

-w, --check-chars=N

compare no more than N characters in lines

-c, --count

prefix lines by the number of occurrences

-i, --ignore-case

ignore differences in case when comparing

-d, --repeated

only print duplicate lines

-s, --skip-chars=N

avoid comparing the first N characters

-f, --skip-fields=N

avoid comparing the first N fields

-u, --unique

only print unique lines

-h, --help

EXTRA

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

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.
