##### **brew bundle**

Usage: brew bundle [subcommand]

Bundler pour les dépendances non-Ruby provenant de Homebrew, Homebrew Cask, Mac App Store, Whalebrew et Visual Studio Code.

**brew bundle [install]:**
    Install and upgrade (by default) all dependencies from the Brewfile.

You can specify the Brewfile location using --file or by setting the $HOMEBREW_BUNDLE_FILE environment variable.

You can skip the installation of dependencies by adding space-separated values to one or more of the following environment variables:
$HOMEBREW_BUNDLE_BREW_SKIP, $HOMEBREW_BUNDLE_CASK_SKIP, $HOMEBREW_BUNDLE_MAS_SKIP, $HOMEBREW_BUNDLE_WHALEBREW_SKIP,
$HOMEBREW_BUNDLE_TAP_SKIP.

**brew bundle upgrade:**
    Shorthand for brew bundle install --upgrade.

**brew bundle dump:**
    Write all installed casks/formulae/images/taps into a Brewfile in the current directory or to a custom file specified with the --file option.

**brew bundle cleanup:**
    Uninstall all dependencies not present in the Brewfile.

This workflow is useful for maintainers or testers who regularly install lots of formulae.

Unless --force is passed, this returns a 1 exit code if anything would be removed.

**brew bundle check:**
    Check if all dependencies present in the Brewfile are installed.

This provides a successful exit code if everything is up-to-date, making it useful for scripting.

**brew bundle list:**
    List all dependencies present in the Brewfile.

By default, only Homebrew formula dependencies are listed.

**brew bundle edit:**
    Edit the Brewfile in your editor.

**brew bundle exec command:**
    Run an external command in an isolated build environment based on the Brewfile dependencies.

This sanitized build environment ignores unrequested dependencies, which makes sure that things you didn't specify in your Brewfile won't get picked up by commands like bundle install, npm install, etc. It will also add compiler flags which will help with finding keg-only dependencies like openssl, icu4c, etc.

**brew bundle sh:**
    Run your shell in a brew bundle exec environment.

**brew bundle env:**
    Print the environment variables that would be set in a brew bundle exec
environment.

##### **brew fetch**

Usage: brew fetch [options] formula|cask [...]

Télécharger une bottle (si disponible) ou les paquets sources pour les formules et les binaires pour les casks. Pour les fichiers, imprimer également les sommes de contrôle SHA-256.

##### **brew gist-logs**

Usage: brew gist-logs [options] formula

Transfère les logs d'un échec de construction de la formule vers un nouveau Gist. Présente un message d'erreur si aucun journal n'est trouvé.

##### **brew home**

Usage: brew home, homepage [--formula] [--cask] [formula|cask ...]

Ouvrir la page d'accueil d'une formule ou d'un cask dans un navigateur, ou ouvrir la page d'accueil de Homebrew si aucun argument n'est fourni.

##### **brew info**

Usage: brew info, abv [options] [formula|cask ...]

Affiche de brèves statistiques sur votre installation Homebrew. Si une formule ou un cask est fournie, afficher un résumé des informations la concernant.

### Commandes externes:

#### brew caveats:

Affiche les avertissements pour toutes les formules installées.

```bash
$ brew tap zgracem/caveats
$ brew caveats

==> libtool
In order to prevent conflicts with Apple's own libtool we have prepended a "g"
so, you have instead: glibtool and glibtoolize.
==> lua
You may also want luarocks:
  brew install luarocks
==> mariadb
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.

MySQL is configured to only allow connections from localhost by default

To connect:
    mysql -uroot

To have launchd start mariadb now and restart at login:
  brew services start mariadb
Or, if you don't want/need a background service you can just run:
  mysql.server start
==> mono
To use the assemblies from other formulae you need to set:
  export MONO_GAC_PREFIX="/usr/local"
```



### Environnement:

- `HOMEBREW_AUTO_UPDATE_SECS`: If set, Homebrew will only check for autoupdates once per this seconds interval.

  *Default:* `300`.

- `HOMEBREW_GITHUB_API_TOKEN`: A personal access token for the GitHub API, used by Homebrew for features such as `brew search`. You can create one at https://github.com/settings/tokens. If set, GitHub will allow you a greater number of API requests. For more information, see: https://developer.github.com/v3/#rate-limiting

  *Note:* Homebrew doesn’t require permissions for any of the scopes.

- `HOMEBREW_NO_AUTO_UPDATE`: If set, Homebrew will not auto-update before running `brew install`, `brew upgrade` or `brew tap`.

- `HOMEBREW_VERBOSE`: If set, Homebrew always assumes `--verbose` when running commands.

- `HOMEBREW_NO_INSTALL_CLEANUP`: Si n'est pas mis, `brew cleanup` est lancé tous les 30 jours.

  

### coreutils (GNU Tools)

Installer la version GNU des outils lignes de commande (OSX utilise la version BSD):

```bash
$ brew install coreutils
```

Les outils GNU sont préfixés par la lettre **g** (**g**ls, **g**cat, **g**chmod...), permettant d'utiliser également leur pendant BSD (ls, cat, chmod...)

*Les outils GNU sont installés dans /usr/local/bin/*

*Un alias sans le préfixe **g** est crée dans /usr/local/opt/coreutils/libexec/gnubin/* ou */opt/homebrew/opt/coreutils/libexec/gnubin*



```bash
❯ ls /opt/homebrew/opt/coreutils/libexec/gnubin/
'['	    
b2sum, base32, base64, basename, basenc, 
cat, chcon, chgrp, chmod, chown, chroot, cksum, comm, cp, csplit, cut
date, dd, df, dir, dircolors, dirname, du, 
echo, env, expand, expr, 
factor, false, fmt, fold, 
groups
head, hostid, 
id, install, 
join
kill
link, ln, logname ,ls
md5sum, mkdir, mkfifo, mknod, mktemp, mv
nice, nl, nohup, nproc, numfmt,
od
paste, pathchk, pinky, pr, printenv, printf, ptx, pwd, 
readlink, realpath, rm, rmdir, runcon,
seq, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, shred, shuf, sleep, sort, split, stat, stdbuf, stty, sum, sync
tac, tail, tee, test, timeout, touch, tr, true, truncate, tsort, tty, 
uname, unexpand, uniq, unlink, uptime, users, 
vdir
wc, who, whoami
yes
```

On peut ajouter le dossier /usr/local/opt/coreutils/libexec/gnubin (/opt/homebrew/opt/coreutils/libexec/gnubin) dans le $PATH. Les outils GNU sont alors disponibles sans préfixe, à la place des outils BSD.

De même pour les man (`MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"`)

```bash
# AVEC PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH"

❯ which ls
/opt/homebrew/opt/coreutils/libexec/gnubin/ls

❯ which gls
/opt/homebrew/bin/gls
(gls -> ../Cellar/coreutils/8.31/bin/gls)

❯ which /bin/ls
/bin/ls

❯ ls --version
ls (GNU coreutils) 9.1

❯ gls --version
ls (GNU coreutils) 9.1


# SANS PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH"

❯ which ls
/bin/ls

❯ which gls
/opt/homebrew/bin/gls

❯ which /bin/ls
/bin/ls

❯ ls --version
ls: illegal option -- -

❯ gls --version
ls (GNU coreutils) 9.1
```

Utiliser date ou gdate:

```bash
gnudate() {
    if hash gdate 2>/dev/null; then
        gdate "$@"
    else
        date "$@"
    fi
}
```



#### findutils (GNU Tools)

Comprend les versions GNU de *find, locate, xargs* (pas de updatedb dans osx )

```bash
$ brew install findutils

# SANS PATH="/opt/homebrew/opt/findutils/libexec/gnubin:$PATH"

$ which find
/usr/bin/find

$ which gfind
/opt/homebrew/bin/gfind

$ gfind --version
find (GNU findutils) 4.9.0

#### 2. Some taps are not on the default git origin branch

`brew doctor` dit:

```bash
Warning: Some taps are not on the default git origin branch and may not receive
updates. If this is a surprise to you, check out the default branch with:
  git -C $(brew --repo shivammathur/extensions) checkout master
```

Lancer `git -C $(brew --repo shivammathur/extensions) checkout master`:

```bash
git -C $(brew --repo shivammathur/extensions) checkout master
.github/scripts/edit.sh: needs merge
.github/workflows/tests-all.yml: needs merge
Formula/vips@7.0.rb: needs merge
Formula/vips@7.1.rb: needs merge
Formula/vips@7.2.rb: needs merge
Formula/vips@7.3.rb: needs merge
Formula/vips@7.4.rb: needs merge
Formula/vips@8.0.rb: needs merge
Formula/vips@8.1.rb: needs merge
error: vous devez d'abord résoudre votre index courant
```

<u>Solution:</u>

If you want to keep the changes you made to those formula there is nothing you need to do. `brew doctor` only provides information and if you don't have problems you don't need to change anything.

If you want to discard the changes, the easiest way would be:

```bash
git -C $(brew --repo shivammathur/extensions) add .
git -C $(brew --repo shivammathur/extensions) reset --hard origin/master
git -C $(brew --repo shivammathur/extensions) checkout master
```

La dernière commande dit:

```bash
HEAD's previous position was on 13d8b20 imap@8.1: update 8.1.0 bottle.
Switching to the 'master' branch
Your branch and 'origin / master' have diverged,
and have 1 and 54 different commits each respectively.
  (use "git pull" to merge the remote branch into yours)
```

Pour corriger, lancer:

```bash
git -C $(brew --repo shivammathur/extensions) reset --hard origin/master
```



#### 3. fatal: It seems that there is already a rebase-merge directory

```bash
fatal: It seems that there is already a rebase-merge directory, and
I wonder if you are in the middle of another rebase.  If that is the case, please try
	git rebase (--continue | --abort | --skip)
If that is not the case, please
	rm -fr ".git/rebase-merge"
and run me again.  I am stopping in case you still have something valuable there.
```

Pour corriger, lancer:

```bash
brew update-reset
```



#### 4. error: Unable to create '/opt/homebrew/Library/Taps/homebrew/homebrew-core/.git/index.lock': File exists.

```bash

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.
error: could not detach HEAD
```

Pour corriger, lancer:

```bash
rm /opt/homebrew/Library/Taps/homebrew/homebrew-core/.git/index.lock
