They're basically the same file, same columns etc, except that the datetime has changed and I've changed one other value to pick up if the diff works.

Here's what I have done so far:

I removed the datetime columns in this way:

Code:
#!/bin/bash
#---------------------------------------------------------------------
#This script removes the datetime stamp and pipes the old file to a new #file
#---------------------------------------------------------------------
awk -v oldfile="$1" -v newfile="$2"'BEGIN{FS=";";OFS=","}{$13=$14=$15=""}1' oldfile > newfile

I then intend to call the script from the command line in this way:

Code:
./script.sh oldfile1.csv newfile1.csv
./script.sh oldfile2.csv newfile2.csv

I do this for the 2 files

Then I use this command to compare the two files (this must also be in a script):

Code:
awk diff newfile1 newfile2 > resultfile

I want to compare the two files excluding the columns that generate the date time stamp.

I only need to see the differences made from file1 to file2 without picking up the timestamp column or then all the data gets selected since this is always changing.

I need all these different commands in scripts.

Can you please help me?
