Using "whitelist" from a file to remove entries
Dear all,
what I need to do is extract an entries list from a file and remove some entries based on a white list present on other file, then output into result.txt file.

Example:

Code:
source.txt:
12345 text1 text2 text3 text4
123 text1 text2 text3 text4
678 text1 text2 text3 text4
987 text1 text2 text3 text4
456 text1 text2 text3 text4

Code:
whitelist.txt
123
987

Code:
output on result.txt file:
12345 text1 text2 text3 text4
678 text1 text2 text3 text4
456 text1 text2 text3 text4

What is the best and fast way to do that?
I can change the CR in whitelist.txt and put a "," like:
123,987
if this can simplify the code...

Many thanks!
