Top Forums Shell Programming and Scripting I want to find the difference between two files, only for the header (column names) Post 302916592 by gull04 on Thursday 11th of September 2014 03:10:08 AM

Hi,

To utilise the method that I've used you'll have to increase the number of column variables and loops to match your first input file. Which is more than the four or so that I was expecting, I have tested this and it will remove the data as required, so you can just increase the initial declarations and for loop count. You'll also have to change the field delimiter to a semicolon.

Not very elegant, but it will work.

Regards

Dave
