Fwd: Q: use '-C' flag with 'git config --global'

Fwd: Q: use '-C' flag with 'git config --global'

[Tomáš Procházka]

Hi,

I'm running into issue that if I run `git -C <pwd/to/showmax/project>
config --global user.email` I don't get expected email.
Expected: tomas.prochazka@showmax.com
Got: tomas.prochazka5d@gmail.com

My config contains a little catch:

~/.gitconfig
```
[user]
       name = Tomáš Procházka
       email = tomas.prochazka5d@gmail.com

[includeIf "gitdir:~/Workspace/Showmax/"]
   path = ~/Workspace/Showmax/.gitconfig
```
~/Workspace/Showmax/.gitconfig
```
[user]
    name = Tomáš Procházka
    email = tomas.prochazka@showmax.com
```

I get correct email setting if I run command without `--global` flag.
But What I understand from the [`git-config`
docs](https://git-scm.com/docs/git-config#_description) if no flag is
passed the values are read from system, global and local.

If I run commands one by one, No returns the ~correct~ expected email:

~ $ git -C <pwd/to/showmax/project> config --system user.email
~ $ git -C <pwd/to/showmax/project> config --global user.email
tomas.prochazka5d@gmail.com
~ $ git -C <pwd/to/showmax/project> config --local user.email

Am I missing something?
Thanks for the answer.

Regards
Tomáš Procházka

Right, I'd expect that to work, but...

There's another difference when asking to read from a specific file:
includes are not turned on by default. Try

  git -C ... config --global --includes user.email

This is covered briefly in git-config(1):

  --[no-]includes
    Respect include.* directives in config files when looking up values.
    Defaults to off when a specific file is given (e.g., using --file,
    --global, etc) and on when searching all config files.

This can be confusing, but was necessary to keep compatibility with
scripted manipulations of those files when includes were introduced.

So, in short, the mention of -C in the report was red herring and it
was all about --(system|global|local)?

Yes. It's relevant insofar as being in the repo to trigger the
conditional include, but "cd" would also have sufficed for that. :)
