Grep regular expression list

Question

I have a large regular expression file, one per line. I would like to invert grep another multiline file against any regular expression that appears in the first file. Something like that:

grep -v fileWithManyRegularExpressions fileThatMightMatchSomeRegularExpressions

Is there an elegant way to do this, besides having to iterate over all regular expressions?

Answer 1

grep -v -f regexes.txt content.txt

Answer 2

At least with Gnu grep you can use --file=<filename>, and everything should be fine.
