I ran a global configuration command in git to exclude certain files using a .gitignore_global file:

git config --global core.excludesfile ~/.gitignore_global

Is there a way to undo the creation of this setting globally?

I'm not sure what you mean by "undo" the change. You can remove the core.excludesfile setting like this:

git config --global --unset core.excludesfile

And of course you can simply edit the config file:

git config --global --edit

...and then remove the setting by hand.

    Just if you have the same key repeated (because you did an --add instead of --edit), this command will not work but you can do `git config --replace-all core.excludesfile "your_value"` – Juan Saravia Jan 30 '15 at 12:04

    I wanted to change this back to "input" but found the existing setting under `system` scope so I used `git config --system --edit` to change my entry. – colin_froggatt May 06 '15 at 13:05

    For Windows, you can edit the file at C:\Users\%USERNAME%\.gitconfig – Shital Shah Oct 27 '16 at 04:50

    In my case, this does not work for some filter settings; I was able to find the file by `git config -l --show-origin` and I went to the file to edit its content. – WesternGun Nov 28 '18 at 15:33
  • @larsks I am afraid the second one will work only if `core.editor` is correct :-) – Alessandro Jacopson Feb 13 '19 at 15:47

You can use the --unset flag of git config to do this like so:

git config --global --unset user.name
git config --global --unset user.email

If you have more variables for one config you can use:

git config --global --unset-all user.name

You can check all the config settings using

git config --global --list

You can remove the setting for example username

git config --global --unset user.name

You can edit the configuration or remove the config setting manually by hand using:

git config --global --edit

  • Place the cursor on the line you want to delete.
  • Type dd and hit Enter to remove the line.

when you finish, type ESQ and :wq

If someone just wanna delete the user object entirely, then he should use:

git config --global --remove-section user

This is useful when a user accidentally adds more properties that are not required just like user.password etc.

You can edit the ~/.gitconfig file in your home folder. This is where all --global settings are saved.

git config information will stored in ~/.gitconfig in unix platform.

In Windows it will be stored in C:/users/<NAME>/.gitconfig.

You can edit it manually by opening this files and deleting the fields which you are interested.
