I want to remove all lines in a file containing a string from another file. So I don't want to remove the lines which are identical, there are none, but remove all lines if they share a string from another file. And write the lines which didn't contain a string from the other file to a new file. Example:
File A:
bird, snake
dog, cat
rabbit,fox
eagle,dove
File B:
dog
dove
RESULT File:
bird,snake
rabbit,fox
Please help.
Thanks a lot.
