How is git configuration evaluated on commit?

I configure My First Git Repo and run;

git config --list

I noticed that I have several entries for specific configuration values;

 core.autocrlf=input [...] core.autocrlf=false

I assume that these values ​​are doubled because they are displayed in several configuration files (system, global, file). My question is which of these values ​​takes precedence? Is the configuration file read line by line and the last record taken as the one used during commit?

Borrowed from MYYN, these are three places where you can find configuration files:

  • $ GIT_DIR / configuration
  • ~ / .gitconfig (- global)
  • $ (prefix) / etc. / gitconfig

Well, imagine that you globally set your email address to niko.schwarz@gmail.com. Now we are creating a new repo:

 $ cd /tmp $ mkdir try && cd try $ git init $ git config user.email niko.schwarz@s-i.ch $ touch hi $ git -add . $ git commit -m 'bla'

Then your user.email will be set to two values:

 $ git config --list | grep niko.schwarz user.email=niko.schwarz@gmail.com user.email=niko.schwarz@s-i.ch

But if you look at the journal, the email address will be set to the one that relates to the repo:

 $ git log | grep niko.schwarz Author: Niko Schwarz < niko.schwarz@s-i.ch > Signed-off-by: Niko Schwarz < niko.schwarz@s-i.ch >

Therefore, local bits are global; this is the order in which the values ​​are listed. Now, turning over a bit, I would suggest that git config -list shows things in the order in which the latter take precedence.

Unless explicitly specified with --file , there are three files where git-config will look for configuration options:

  • $GIT_DIR/config

  • ~/.gitconfig ( --global )

  • $(prefix)/etc/gitconfig

If no additional parameters are specified, all read parameters will read all these available files. If a global or system-wide configuration file is not available, they will be ignored.

The .git/config file in each repository is used to store the configuration for this repository, and $HOME/.gitconfig used to store the configuration for each user as backup values ​​for the .git/config file. The /etc/gitconfig can be used to store the system-wide default configuration.

Excellence should be from the most general to the repository related entries.

Or more memorable (borrowed from Niko): local beats global
