How can I find all files with a certain line in the source?

Question

I am using linux trying to find all files that contain the phrase "Hello" in them (not the filename) and then delete them all. How can I do this?

Answer 1

grep --recursive --files-with-matches Hello $HOME | xargs -d '\n' rm -f

当然，您需要确保grep仅找到要删除的文件，因为此管道完全无法原谅错误

Answer 2

It took me 5 seconds to find google it:

find . -exec grep -n hello /dev/null {} \\;

Of course, I could be lying and that could format your hard disk :^)
