I have just signed in at daniweb, I hope you can help me. I am new to perl and have the following problem to solve:
I have loads of files with 16 columns full of numbers. I need to
1. take column 6 and substract column 10, store the difference column in a new column
2. then delete all columns and just leave the first and this difference column in the file
I know this is very easy to do in any mathematical program or openofficeCalc but since I have to do it like for hundreds of file I really need a program that does this for me.
I would be really grateful if someone could help me.
