Question

# To fix the symptom

How can you sum up the following columns effectively?

Column 1

1
3
3
...   

Column 2

2323
343
232
...

This should give me

Expected result

2324
346
235
...

I have the columns in two files.

# Initial situation

I use sometimes too many curly brackets such that I have used one more this { than this } in my files.
I am trying to find where I have used the one unnecessary curly bracket.
I have used the following steps in getting the data

Find commands

 find . * -exec grep '{' {} + > /tmp/1
 find . * -exec grep '}' {} + > /tmp/2

AWK commands

 awk -F: '{ print $2 }' /tmp/1 > /tmp/11
 awk -F: '{ print $2 }' /tmp/2 > /tmp/22

The column are in the files /tmp/11 and /tmp/22.

I repeat a lot of similar commands in my procedure.
This suggests me that this is not the right way.

Please, suggests me any way such as Python, Perl or any Unix tool which can decrease the number of steps.

Answer 1

If c1 and c2 are youre files, you can do this:

$ paste c1 c2 | awk '{print $1 + $2}'

Or (without AWK):

$ paste c1 c2 | while read i j; do echo $(($i+$j)); done
