What is this directory "$(brew --prefix)"? (homebrew)
Hello,
I installed the package manager called homebrew a few days ago. Everything seems to be working fine but today I've just noticed this funny looking directory $(brew --prefix). I'm not sure if I made a mistake and duplicated this directory from somewhere else, or if it's suppose to be there.
Executing the the brew commands "Display the real path to your Homebrew prefix" and "Display the real path to your Homebrew Cellar
So Looking at this, is /Users/m/$(brew --prefix) a redundant duplicate I somehow made which I can now delete? Or is that dollar sign in front of a directory name meaning something else I am not understanding?
It looks like an installer error, the $(...) notation is similar to the `...` backtick notation. Try
If homedir is in the listing then your shell doesn't support the $(...) expansion (though it should as this is in the Posix std AFAIK
Unless you changed your shell to something else, MacOS's default shell (bash) quite definitely supports $() notation.
On shells that don't support it, it would be a syntax error, it wouldn't just use it literally. They'd have to put it into single quotes or escape everything to make it do that.
So I suspect a bad script or typing mistake, not an incompatible shell.
