Hi, list How can I search git log with ceratin keyword_a but without keyword_b? Assume I have a branch master with 3 commits, the comments are t123, b1 and b12 separately, that is: b90b03f (HEAD -> master) b12 27f7577 b1 7268b40 t123 And now, I want to use git log --grep to search the log with the keyword "12" but without t123. The result I want is b90b03f b12 How can I achieve this? Thank you for your attention to this matter.
