Shell Programming and Scripting

hi i have file 1 as follows:

Code:

6
7
8
9
10

i have file 2 as follows:
5
5
5
5
5
[/code]

i want file 3 as follows:

Code:

-1
-2
-3
-4
-5

i am subtracting every row from one file from every row from the second file and saving it to another file..i would like to use awk to do this..

so far i have:

Code:

awk '{for(i=1; i<=NF; i++) {val[i]=$1} {printf("%1.11f",val[i])}}' col > try #file1
awk '{for(i=1; i<=NF; i++) {val[i]=$1} {printf("%1.11f",val[i])}}' col1 > try1 #file2

since awk loses the variable from one statement to another, is there any way i can combine the two statements together and perform the subtraction?

thanks in advance.

Code:

% head file[12]
==> file1 <==
6
7
8
9
10

==> file2 <==
5
5
5
5
5
% awk 'getline f1 < "file1" { print $1 - f1 }' file2
-1
-2
-3
-4
-5

it worked!! thanks for your help!

Code:

paste file1 file2 | awk '{ print $2 - $1 }' > file3

Or:

Code:

% paste -d- file2 file1|bc            
-1
-2
-3
-4
-5
