Dynamic Array Issue

Could one of you, please, provide some input regarding my problem below and it is as follows:

I have 2 files that I need to make sure are identical before processing:

First, I sort both files

Second, I do a diff file1 file2 > File 3
This provides me with the difference.

Now, I need to read File 3 - into an array and remove the difference from both files - if any

filename = /.../.../.../... #input file
set -A <array_name> [ < $filename]

Could I use the sed '/expression/' to remove the line???


Please advise.

Don
