grep: Show ALL lines before a match

Not only 10, or 7, or 14 for example, as explain in this topic and in many others: https://stackoverflow.com/questions/12444808/how-do-i-fetch-lines-before-after-the-grep-result-in-bash/12444813 How you do it? For example, instead of: … | grep -B 10 — "foo" I want: … | grep -B — "foo" But this last code doesn’t work.
