Hey Gang!
So I have two Arrays. @linecount and @hit . Now these arrays contain numbers which I'm using as line placeholders on files. I need these two arrays to sync up and not repeat a number.
Here are the contents (spam alert)
@linecount

Notice how some of them have the same numbers, multiple times? I need it to quit that and merge them into a singular array with no duplicating numbers.
I hope this makes sense.
Something like this:
@merge{@linecount, @hit} = (1) x @linecount + @hit;
@all_unique = sort { $a <=> $b } keys %merge;

Hi
you can place the two arrays in two files- file1 and file2.
cat file2 >> file1
sort -nu file1

[house@leonov] paste data1 data2 | awk 'BEGIN {X=0} {if (X!=$1) {print $0; X=$1}}'

$ cat adelsin_1.txt

$ cat adelsin_2.txt

$ join -a 1 -a 2 adelsin_1.txt adelsin_2.txt | uniq

Thank you all for you responses. I'm looking at keep this answer primarily OS independant. Radoulov's answer seemed to work the best for me.
Additional question, how do I do the same thing with words and a single file?

The question is in the answer.
my %hash = map { $_, 1 } @names;
my @name_final = keys %hash;
I wish I fully understood hashes.
(Not sure I'm getting you right, though ...)
