See linkgit:git-update-index[1]. `keep` by default.
core.checkStat::
- Determines which stat fields to match between the index
- and work tree. The user can set this to 'default' or
- 'minimal'. Default (or explicitly 'default'), is to check
- all fields, including the sub-second part of mtime and ctime.
+ When missing or is set to `default`, many fields in the stat
+ structure are checked to detect if a file has been modified
+ since Git looked at it. When this configuration variable is
+ set to `minimal`, sub-second part of mtime and ctime, the
+ uid and gid of the owner of the file, the inode number (and
+ the device number, if Git was compiled to use it), are
+ excluded from the check among these fields, leaving only the
+ whole-second part of mtime (and ctime, if `core.trustCtime`
+ is set) and the filesize to be checked.
++
+There are implementations of Git that do not leave usable values in
+some fields (e.g. JGit); by excluding these fields from the
+comparison, the `minimal` mode may help interoperability when the
+same repository is used by these other systems at the same time.
core.quotePath::
Commands that output paths (e.g. 'ls-files', 'diff'), will
branch to track another branch.
This option defaults to never.
+branch.sort::
+ This variable controls the sort ordering of branches when displayed by
+ linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
+ value of this variable will be used as the default.
+ See linkgit:git-for-each-ref[1] field names for valid values.
+
branch.<name>.remote::
When on branch <name>, it tells 'git fetch' and 'git push'
which remote to fetch from/push to. The remote to push to
order of the value. You may use the --sort=<key> option
multiple times, in which case the last key becomes the primary
key. The keys supported are the same as those in `git
- for-each-ref`. Sort order defaults to sorting based on the
+ for-each-ref`. Sort order defaults to the value configured for the
+ `branch.sort` variable if exists, or to sorting based on the
full refname (including `refs/...` prefix). This lists
detached HEAD (if present) first, then local branches and
- finally remote-tracking branches.
+ finally remote-tracking branches. See linkgit:git-config[1].
--points-at <object>::
This format will remain stable across Git versions and regardless of user
configuration. See below for details.

+--quiet::
+ With 'add', suppress feedback messages.
