### 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

### Erreurs:

<u>Solution:</u> Lancer **brew update-reset** pour réparer:

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

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
```
