Where can I find the installed package path via brew

Question

I installed some packages via brew. But I can not find where they are.

I can not get access by typing hping on terminal

% brew install hping
(git)-[master] 
Warning: hping-3.20051105 already installed

Answer 1

Use the following to show the installation path of a package:

brew info hping

Example output:

pcre: stable 8.35 (bottled)
http://www.pcre.org/
/usr/local/Cellar/pcre/8.35 (146 files, 5.8M) *
  Poured from bottle
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/pcre.rb
==> Options
--universal
    Build a universal binary

Answer 2

To figure out where your formula is installed, do brew --prefix hping

You can also relink your hping binary by doing brew unlink hping && brew link hping

Also maybe your $PATH is not well defined. Does the list given by echo $PATH contains the result given by echo $(brew --prefix)'/bin:'$(brew --prefix)'/sbin'? This path should be toward the beginning of the list to be prioritized over system binaries, surely before /usr/bin.

To do so, you can add this at the end of your ~/.zshrc or ~/.bashrc:

export PATH=$(brew --prefix)/bin:$(brew --prefix)/sbin:$PATH

As a result, after opening a new terminal or doing source ~/.zshrc, you'll be able to echo your correct path as:

$ echo $PATH
/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin

Answer 3

The /usr/local/Cellar directory is the default location on OS X. You'll see sub-directories in there for all your installed formulae.

Answer 4

Normally, homebrew installs packages into /usr/local/bin. So you need to check that your PATH contains that directory, like this:

echo $PATH

Also, try running

brew doctor

to make sure your setup is correct. If /usr/local/bin is not in your PATH, you need to edit ~/.profile and add a line like this:

export PATH=$PATH:/usr/local/bin

Then start a new Terminal (in order to re-read your login profile) and try again.

If all that fails, it must be installed somewhere else. You can search for it by running a command like this:

sudo find / -name hping -type f

Answer 5

Try this command

brew --cellar <FORMULA>

e.g.

brew --cellar hping

Answer 6

To find your base installation directory for Homebrew, use one of the following commands:

brew --prefix
brew --cellar

The latter specifically returns the path of your Cellar folder.

Answer 7

I couldn't find any direct CLI option in brew to get the full path to the currently installed version of a formula but this would work as long as you are using bash:

echo $(brew --cellar asciidoctor)/$(brew info --json asciidoctor | jq -r '.[0].installed[0].version')
# /usr/local/Cellar/asciidoctor/1.5.8

Answer 8

Inspired by @RubenLaguna, I came up with this to get the full path to the installed version of the default formula.

As shown in previous answers, to get the install path for a formula:

brew --prefix nmap

Returns a symlink to the install path:

/usr/local/opt/nmap

To expand the full path:

readlink -f $(brew --prefix nmap)

/usr/local/Cellar/nmap/7.92

Answer 9

hping requires root privileges to run.

You probably need to add /usr/local/sbin to your PATH.

When I ran brew doctor:

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so
    echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.bash_profile

Answer 10

I recommend adding the following line to your ~/.bash_profile (or the equivalent configuration file if you are using a different shell):

export HOMEBREW_CASK_OPTS="--appdir=/Applications"

Answer 11

I installed some packages via brew. But I can not find where they are.

It seems that homebrew requires one to be explicit with things. Fortunately, a bit of escaping using brew --prefix can make this a no-brainer, for those who need to find the path for the pkg-config utility, e.g.

PKG_CONFIG_PATH=`brew --prefix hping`/lib/pkgconfig/ pkg-config --cflags hping

(Except this isn't going to work anyway, because it seems hping doesn't come with hping.pc .. although, in the case where package maintainers do put .pc files, this trick can be useful.)

Answer 12

If someone looking for real path of package:

In my case brew --cellar opencv3 gives /usr/local/Cellar/opencv

But find /usr/local/Cellar/ -type d -name "*opencv*" -maxdepth 1 gives

/usr/local/Cellar//opencv3(which is /usr/local/Cellar/opencv3 actually).

Headers:

/usr/local/Cellar/opencv3/3.4.1_1/include/

Libs:

/usr/local/Cellar/opencv3/3.4.1_1/lib/

Answer 13

For anyone that lands here after googling, and/or for anyone who wants a list of packages that are installed as keg only, you can get this info from the brew JSON output.

List all installed packages:

brew info --json --installed

List keg only packages (jq tool required):

brew info --json --installed | jq -r '.[] | select(.keg_only == true) | .name'

List the path for keg only packages (again, jq tool required):

brew info --json --installed | jq -r '.[] | select(.keg_only == true) | .name' | while read name; do brew --prefix $name; done 

Answer 14

brew list opencv

Output like this:

/usr/local/Cellar/opencv/4.5.2_4/bin/opencv_annotation
/usr/local/Cellar/opencv/4.5.2_4/bin/opencv_interactive-calibration
/usr/local/Cellar/opencv/4.5.2_4/bin/opencv_model_diagnostics
...

My brew version:

brew -v
> Homebrew 3.2.1
