What config values are actually being used by git?

Question

To see all of the git config values you can use:

git config --list --show-origin

My question is this. If core.autocrlf shows up multiple times (some true and some false). Which value is actually being used? Is there a command that shows you the "effective" git config value being used for every config value?

Searching I found:

• How to obtain the effective git-config values and their source? - I thought this would be the answer to my question but it just shows how to use git config --list --show-origin. This points to

• Where do the settings in my Git configuration come from? - This nicely explains how there are multiple git locations but it doesn't say what the effective value is.

NOTE: It appears by experimentation that

git config --get core.autocrlf

Gives me the effective value (for the one config property core.autocrlf).

Is there a command that gives you the effective value for all config properties?

Answer 1

If you go with git config --list, you will get all settings, global, local. For specific git project you can use

git config -l --local --show-origin

The same way with --global you could see your global settings (applied if you are not modifing any configuration for the project).

The 'magic' behind this is that there is a global settings that can be overriden by a local project settings. The most common thing is to set your email. Git wants you to set it globally first

git config --global user.email john@example.com

Then you will start a new project and this global configuration is automatically inhereted. But now you have the possibility to change it

git config user.email peter@example.com

and now you will see two user.email rows while git confg --list. The global will be the first one and the second one will be local, because it overrides the first value. Using --local git will retrieve only the final data for your local project.
