I have multiple files (66) and want to divid column 3 of each file to its corresponding value in the info.file and insert the new value in column 4 of each file. 
My manual code is:

```
awk '{print $4=$3/NUmber from info.file}1' file 

```

But this takes me hours to do for each individual file. So I want to automate it for all files. Thanks

```
file1:
 chrm  name  value
 4     a      8
 3     b      4

file2:
 chrm  name  value  
 3     g      6       
 5     s      12       

info.file:
 file_name    average
 file1          8
 file2          6
 file3          10

```

output: 

```
 file1:
 chrm  name  value  new_value
 4     a      8       1
 3     b      4       0.5

 file2:
 chrm  name  value  new_value
 3     g      6       1
 5     s      12      2

```
