Selecting Unique Values from many List
I have a question
I have like 19 different list which contains the name of the server but what I need is just unique ones.
First thing I need to do is just make a unique list within the list itself
i.e. delete anything that is repeated inside the list
like for example
in list1
i have
a
b
c
d
e
a
c
f
g
h
so i just need is a b c d e f g h i mean unique values which is easier anyone can do it i guess.
For the first list its ok
Like that i have 19 liist and i have to do that the same thing which is ok not that hard
the problem is now,
there should not be anything repeating in any one of those list
i.e. if something is there in the first list means that should not be in 2nd list and so on. so that means
for the first list its ok i dont need to do anything as it is after deleting the duplicates
second list I have to compare with the first list and delete if anything from the first list
third list i have to compare with first and second list and anything present in first or second list I have to delete from third list and so on upto 19 list
Plz can anyone suggest me how can i do that
let me know if anything confusing
just i want is not repeated in any one of those 19 list i hope thats pretty much clear
Thanks In advance
its serious problem im having

lreplace
lreplace(n) Tcl Built-In Commands lreplace(n)
__________________________________________________________________________________________________________________________________________________
NAME
lreplace - Replace elements in a list with new elements
SYNOPSIS
lreplace list first last ?element element ...?
_________________________________________________________________
DESCRIPTION
lreplace returns a new list formed by replacing one or more elements of list with the element arguments. first and last specify the first
and last index of the range of elements to replace. 0 refers to the first element of the list, and end (or any abbreviation of it) may be
used to refer to the last element of the list. If list is empty, then first and last are ignored.
If first is less than zero, it is considered to refer to the first element of the list. For non-empty lists, the element indicated by
first must exist.
If last is less than zero but greater than first, then any specified elements will be prepended to the list. If last is less than first
then no elements are deleted; the new elements are simply inserted before first.
The element arguments specify zero or more new arguments to be added to the list in place of those that were deleted. Each element argu-
ment will become a separate element of the list. If no element arguments are specified, then the elements between first and last are sim-
ply deleted. If list is empty, any element arguments are added to the end of the list.
