Doing ls -ltra /usr/local gives a lot of homebrew files and folders in /usr/local itself, as opposed to a subfolder:

CODEOFCONDUCT.md, LICENSE.txt, README.md, .git, .gitignore, Library, bin, opt, Cellar and probably other files and folders refer to homebrew.

Is this normal for homebrew when I chose "Install" for Xcode, and then installed homebrew as per the following?

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
==> This script will install:
/usr/local/bin/brew
/usr/local/Library/...
/usr/local/share/man/man1/brew.1

Press RETURN to continue or any other key to abort
==> /usr/bin/sudo /bin/mkdir /usr/local

WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.

To proceed, enter your password, or type Ctrl-C to abort.

Password:
==> /usr/bin/sudo /bin/chmod g+rwx /usr/local
==> /usr/bin/sudo /usr/bin/chgrp admin /usr/local
==> /usr/bin/sudo /bin/mkdir /Library/Caches/Homebrew
==> /usr/bin/sudo /bin/chmod g+rwx /Library/Caches/Homebrew
==> Installing the Command Line Tools (expect a GUI popup):
==> /usr/bin/sudo /usr/bin/xcode-select --install
xcode-select: note: install requested for command line developer tools

For what it's worth, I've also installed cask.

    Looks normal. Can have clashes with non-homebrew software. That's why some prefer homebrew install elsewhere. – Gilby Jul 13 '16 at 6:01

Yes. That's how homebrew does.

You can usually trust

brew doctor

to tell if things are correct - it is pretty good about flagging anything amiss in /usr/local.

But to confirm your main question, the normal for homebrew it that it's noted for being "chatty" in that directory with many files and folders.

  • Also, you can save your brew list and blow away the installation, purge /usr/local and then watch what gets installed going forward... – bmike Jul 16 '16 at 11:30

Yes, homebrew adds some files and folders to /usr/local. You can see the full list in the root of the github repository https://github.com/homebrew/brew:

.github
Library
bin
etc/bash_completion.d
share
.gitignore
.travis.yml
.yardopts
CODEOFCONDUCT.md
LICENSE.txt
README.md
  • very nice list and explanation - less hand waving than my answer, too! – bmike Jul 21 '16 at 1:13
