git-apply - Apply a patch to files and/or to the index
git apply [--stat] [--numstat] [--summary] [--check] [--index | --intent-to-add] [--3way]
[--apply] [--no-add] [--build-fake-ancestor=<file>] [-R | --reverse]

[-p<n>] [-C<n>] [--inaccurate-eof] [--recount] [--cached]

[--exclude=<path>] [--include=<path>] [--directory=<root>]
[--verbose] [--unsafe-paths] [<patch>...]
Reads the supplied diff output (i.e. "a patch") and applies it to files. When running from a subdirectory in a repository, patched paths outside the directory are ignored. With the --index option the patch is also applied to the index, and with the --cached option the patch is only applied to the index. Without these options, the command applies the patch only to files, and does not require them to be in a Git repository.
This command applies the patch but does not create a commit. Use git-am(1) to create commits from patches generated by git-format-patch(1) and/or received by email.

is in effect, or when applying the patch (which is the default when none of the options that disables it is in effect), make sure the patch is applicable to what the current index file records. If the file to be patched in the working tree is not up to date, it is flagged as an error. This flag also causes the index file to be updated.
Apply a patch without touching the working tree. Instead take the cached data, apply the patch, and store the result in the index without using the working tree. This implies
When applying the patch only to the working tree, mark new files to be added to the index later (see
git-add(1)). This option is ignored unless running in a Git repository and

When the patch does not apply cleanly, fall back on 3-way merge if the patch records the identity of blobs it is supposed to apply to, and we have those blobs available locally, possibly leaving the conflict markers in the files in the working tree for the user to resolve. This option implies the

When a pure mode change is encountered (which has no index information), the information is read from the current index instead.

Without this option, pathnames with "unusual" characters are quoted as explained for the configuration variable

When applying a patch, ignore additions made by the patch. This can be used to extract the common part between two files by first running
on them and applying the result with this option, which would apply the deletion part but not the addition part.
Historically we did not allow binary patch applied without an explicit permission from the user, and this flag was the way to do so. Currently we always allow binary patch application, so this is a no-op.
Don't apply changes to files matching the given path pattern. This can be useful when importing patchsets, where you want to exclude certain files or directories.

patterns are used, they are examined in the order they appear on the command line, and the first match determines if a patch to each path is used. A patch to a path that does not match any include/exclude pattern is used by default if there is no include pattern on the command line, and ignored if there is any include pattern.
When applying a patch, ignore changes in whitespace in context lines if necessary. Context lines will preserve their whitespace, and they will not undergo whitespace fixing regardless of the value of the
option. New lines will still be fixed, though.
When applying a patch, detect a new or modified line that has whitespace errors. What are considered whitespace errors is controlled by
configuration. By default, trailing whitespaces (including lines that solely consist of whitespaces) and a space character that is immediately followed by a tab character inside the initial indent of the line are considered whitespace errors.
By default, the command outputs warning messages but applies the patch. When

do not correctly detect a missing new-line at the end of the file. As a result, patches created by such
programs do not record incomplete lines correctly. This option adds support for applying such patches by working around this bug.
Report progress to stderr. By default, only a message about the current patch being applied will be printed. This option will cause additional information to be reported.
Do not trust the line counts in the hunk headers, but infer them by inspecting the patch (e.g. after editing the patch without adjusting the hunk headers appropriately).
Prepend <root> to all filenames. If a "-p" argument was also passed, it is applied before prepending the new root.
For example, a patch that talks about updating

git apply --directory=modules/git-gui.
By default, a patch that affects outside the working area (either a Git controlled working tree, or the current working directory when "git apply" is used as a replacement of GNU patch) is rejected as a mistake (or a mischief).

flag is given from the command line, this configuration item is used as the default.
If the patch contains any changes to submodules then git apply treats these changes as follows.
If --index is specified (explicitly or implicitly), then the submodule commits must match the index exactly for the patch to apply. If any of the submodules are checked-out, then these check-outs are completely ignored, i.e., they are not required to be up to date or clean and they are not updated.
If --index is not specified, then the submodule commits in the patch are ignored and only the absence or presence of the corresponding subdirectory is checked and (if possible) updated.
