Top Forums Shell Programming and Scripting I want to find the difference between two files, only for the header (column names) Post 302916439 by Praveen Pandit on Wednesday 10th of September 2014 05:46:03 AM

Hi Don Cragun,

I am still doing some research on this to get the clue.

Regards
Praveen

---------- Post updated at 04:46 AM ---------- Previous update was at 03:33 AM ----------

I am able to read the first line from feed.txt and compare it with declaration.txt and print the difference.

But I am still not able to find the position of the column and its values and remove it. Not sure how to handle multiple new columns and remove it, if found.

Please help.

Thanks & regards
Praveen
