Question Shell Scripting | Return list of unique characters in files

Hi,

I am trying to script the below, but I am not very good at it Smilie

Your help would be greatly appreciated.

1. read all files in the directory in strings
Code:
strings *.*

2. in each file, for each line that contains "ABCD", store characters located at position 521 and 522 of this line (this is where I am stuck)

3. once all files have been read, print a list of unique values (I guess I would have to use uniq).
