UNIX for Dummies Questions & Answers

Hi i have two files
say file 1 contents are
A
B
C
D
E


I have file2 contents are
B
E
F
G
C
K

I want to have new file like
A
B
C
D
E
F
G
K
Please tell me how to achieve this i tried not equal to contition while checking the files but not working as it goes into n * n combinations
Thanks in advance

You want a unique list of the contents of two files:

Code:

sort -u file1 file2 > newfile

Thank you very much for your reply. it is working but the format is getting hay way
i do not want it alphabetically. I think my example that i have given is confusing
say for instance
File 1
J
O
B
H
I
File 2
R
A
H
K
O

File3 should have
J
O
B
H
I
R
A
K

That is i want file 1 contents first and then file 2 but no repetetions
Hope this is much clear
Thanks in advance

Code:

# t.sh
awk 'FILENAME=="file1" {arr[$0]=$0; print $0}
     FILENAME=="file2" {
           if($0 in arr) {continue;}
           print $0
     }' file1 file2

output:

Thank you very much for your reply
