How to change a number on a specific line with cshell or shell?
Hello all,
I need to change a number in a file by adding some residuals respectively
To make it clear,
I need to add 0.11 to the number between 24-28 (which is below the SECON) for all the lines starting with FRR1
or I need to add 0.13 to the number between 24-28 (which is below the SECON) for all lines starting with FRR4
The values for the codes (FRR1, FRR4...) are constant.
since the columns are vary from line to line I try to set the characters between 24-28 so that the code would change only the second...
I tried this code but it is ofcourse useless
and here is the example of my file
Could anyone help please...
