Code:
grep -v a2 a1

this shud get u going..

u can use ur master and bad sector file and get the good records

Code:
lets say
master file = m, bad record=b
cat m > result
cat b >> result
uniq -u result

this will only give u good results.
Code:
-u Displays only lines not duplicated (uniq lines).

Assuming each record is unique and that the output order does not matter:

Code:
cat file.txt bad.txt | sort |uniq -u



Or sort each file before the "comm".
Code:
cat file.txt | sort >file.sor
cat bad.txt  | sort >bad.sor
comm -23 file.sor bad.sor

Please don't use 'l33t sp33k' - this isn't twitter. Plain English. If English is a problem for you we have translation services. That is what corona is telling you.

However:
Quote:
Note: 'uniq' does not detect repeated lines unless they are adjacent.
You may want to sort the input first, or use `sort -u' without `uniq'.
