git-apply - Linux
Overview
git-apply
applies a patch to the current working tree. It can be used to apply a patch that you have created yourself, or to apply a patch that you have received from someone else.
Syntax
git apply [options] <patch>...
Options/Flags
-v, --verbose
: Show the diff that would be applied by the patch.-C, --check
: Check if the patch would apply cleanly. Do not actually apply the patch.-3, --three-way
: Use a three-way merge to apply the patch. This can be useful if the patch conflicts with local changes.-f, --force
: Force the patch to be applied, even if it conflicts with local changes.
Examples
To apply a patch from a file:
git apply patch.patch
To apply a patch from a URL:
git apply https://example.com/patch.patch
To check if a patch would apply cleanly:
git apply --check patch.patch
To force a patch to be applied, even if it conflicts with local changes:
git apply --force patch.patch
Common Issues
One common issue that you may encounter when applying a patch is that it conflicts with local changes. This can happen if you have made changes to the same files that the patch modifies. If this happens, you can use a three-way merge to resolve the conflict.
Another common issue is that the patch may not apply cleanly. This can happen if the patch is for a different version of the code than you are currently using. If this happens, you can try using the --force
option to force the patch to be applied.
Integration
git-apply
can be used with other Git commands to perform more complex tasks. For example, you can use git-apply
to apply a patch to a specific commit:
git apply --index <commit> patch.patch
You can also use git-apply
to create a new branch from a patch:
git apply --branch new-branch patch.patch
