I'm new at scripting, and i need help with this:

I have a "table.txt" file that has this:

00          02          03          04         05          06          07

and i need to append lines in this file, corresponding to each column.

Example:

A = 10
B = 20
result00 = A+B

In table...:

00           02         03          04          05          06          07
${result00}

and i need to do it with all 7 columns. Each column has a different value, from a different variable.

The final file, need to have 400 lines.

I need a table like that:

00           02         03          04          05          06          07
15           20         53          100         430         100         12
[...]        [...]      [...]       [...]       [...]       [...]       [...]
403          212        21          43          50          202         10

Where do the variables come from? – Zanna Oct 18 '17 at 17:16
@Zanna before it, i need to count lines of a bunch of files in a directory, and the number of lines is the result that i need to append in this text table. Each position in the table need to have a result of a number of lines in a unique file. I need only to know how to append this result. – b3g1nn3er Oct 18 '17 at 17:54
