diff reports differences between two files and what has to happen to change the first file into the second. If a record appears in the first file but not the second, diff reports the line(s) on the first file a d and the line where they used to be on the 2nd file
A record on the 2nd file but not the first, a a reports the line number of the first file and the records added.
File 1 contains (actually 1 per line) 1 3 5 9 10 11 12 23 48 and
File 2 contains (actually 1 per line) 2 4 6 8 9 yy 10, the output from diff will be
Only lines starting with ">" or "<" appear in one file but not the other. You should never have a change where you have both symbols and a "---" line.
NR == 1 ... while it is reading the first line of the first file do everything in the curly brackets - YES
The for loop changes the value of n from the total number of pieces resulting from split to 0 - YES
F1 is an associative array containing different pieces from array T as it goes through the loop, i.e. all the numbers from file1 that I need - YES - in its index
next tells it go to the next line, which ends the NR == 1 condition, and starts reading file2 since there is only one line in file1 - YES
It then reads file2 where it checks for every line if it does not match any of the elements of array F1 - YES
