UNIQX(1)

NAME
	uniqx

SYNOPSIS
	uniqx [-udcrf] [-F sep] [-k key,key,...] [file]

DESCRIPTION
	Uniq is buggy and too poor, so I wrote new one.

	flags:
	-u 	# print only unique line
	-d	# print only duplicated line
	-c	# add count of duplicated line in printing
	-r	# print last line of duplicated line
	-f	# field wise comparison (default is column wise comparison)
	-F sep # Field separator
	-k key,key,...

	key:
	key specifies the fields to compare.
	key follows Python like syntax of range.
	n:m	# the meaning is n,n+1,...,m-1
	:m	# the meaning is 0:m
	n:	# the meaning is n to last
	:	# the meaning is 0 to last
	n	# the meaning is single field.
	n begins with 0

	Compatibility to uniq:
	I tried to support syntax of uniq, but it makes the code dirty.
	I gave up.

	The relation to uniq:
		uniq +n
	is same as
		uniqx -k n:
	and
		uniq -n
	is same as
		uniqx -fk n:
