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

colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
