But you see that’s exactly what you are, because you can’t refactor Java code with what you call “Unix tools”. So your only option is to install actual IDEs on Unix.

And “find usages” finds... actual usages (e.g. method calls), not simple text matches which can end up being 80% noise. For `grep -r` you might try `Ctrl+Shift+f` instead.
