Revert changes to a file in a commit
I want to revert changes made by a particular commit to a given file only.
Can I use git revert co开发者_JAVA技巧mmand for that?
Any other simple way to do it?
The cleanest way I've seen of doing this is described here
git show some_commit_sha1 -- some_file.c | git apply -R
Similar to VonC's response but using git show
and git apply
.
Assuming it is ok to change the commit history, here's a workflow to revert changes in a single file in an earlier commit:
For example, you want to revert changes in 1 file (badfile.txt
) in commit aaa222
:
aaa333 Good commit
aaa222 Problem commit containing badfile.txt
aaa111 Base commit
Rebase on the base commit, amend the problem commit, & continue.
1) Start interactive rebase:
git rebase -i aaa111
2) Mark the problem commit for edit in the editor by changing pick
to e
(for edit):
e aaa222
pick aaa333
3) Revert changes to the bad file:
git show -- badfile.txt | git apply -R
4) Add the changes & amend the commit:
git add badfile.txt
git commit --amend
5) Finish the rebase:
git rebase --continue
git revert
is for all file contents within a commits.
For a single file, you can script it:
#!/bin/bash
function output_help {
echo "usage: git-revert-single-file <sha1> <file>"
}
sha1=$1
file=$2
if [[ $sha1 ]]; then
git diff $sha1..$sha1^ -- $file | patch -p1
else
output_help
fi

Note:
another way is described here if you have yet to commit your current modification.
git checkout -- filename
git checkout
has some options for a file, modifying the file from HEAD, overwriting your change.
Dropped.on.Caprica mentions in the comments:
You can add an alias to git so you can do
git revert-file <hash> <file-loc>
and have that specific file be reverted.
See this gist.
[alias]
revert-file = !sh /home/some-user/git-file-revert.sh
Much simpler:
git reset HEAD^ path/to/file/to/revert
then
git commit --amend
and then
git push -f
the file is gone and commit hash, message, etc is the same.
I would simply use the --no-commit
option to git-revert
and then remove the files you don't want reverted from the index before finally committing it. Here's an example showing how to easily revert just the changes to foo.c in the second most recent commit:
$ git revert --no-commit HEAD~1
$ git reset HEAD
$ git add foo.c
$ git commit -m "Reverting recent change to foo.c"
$ git reset --hard HEAD
The first git-reset
"unstages" all files, so that we can then add back just the one file we want reverted. The final git-reset --hard
gets rid of the remaining file reverts that we don't want to keep.
git reset HEAD^ path/to/file/to/revert/in/commit
The above command will take file out of commit, but it will reflect in git status
.
git checkout path/to/file/to/revert/in/commit
The above command will revert the changes (as a result you get file same as HEAD).
git commit
(Pass --amend
to amend commit.)
git push
With this, the file which is already in the commit is removed and reverted.
The above steps should be followed from the the branch where the commit is made.
If you'd like to reset the changes on a file from your last commit, this is what I'm usually using. I think this is the simplest solution.
Please note that the file will be added to the staging area.
git checkout <prev_commit_hash> -- <path_to_your_file>
Hope it helps :)
You can follow this procedure:
git revert -n <*commit*>
(-n
revert all the changes but won't commit them)git add <*filename*>
(name of the file/s you want to revert & commit)git commit -m 'reverted message'
(add a message for reverting)- after committing discard the other files changes so the files stay updated with the changes you committed before the revert
