I am using git and working on master branch. This branch has a file called app.js
.
I have an experiment
branch in which I made a bunch of changes and tons of commits. Now I want to bring all the changes done only to app.js
from experiment
to master
branch.
How do I do that?
Once again I do not want a merge. I just want to bring all the changes in app.js
from experiment
branch to master
branch.
This question is related to
git
git-checkout
# check out all files in <paths> from branch <branch_name>
git checkout <branch_name> -- <paths>
Source: http://nicolasgallagher.com/git-checkout-specific-files-from-another-branch/.
See also man git checkout
.
Examples:
# Check out "somefile.c" from branch `my_branch`
git checkout my_branch -- somefile.c
# Check out these 4 files from `my_branch`
git checkout my_branch -- file1.h file1.cpp mydir/file2.h mydir/file2.cpp
# Check out ALL files from my_branch which are in
# directory "path/to/dir"
git checkout my_branch -- path/to/dir
If you don't specify, the branch_name
it is automatically assumed to be HEAD
, which is your most-recent commit of the currently-checked-out branch. So, you can also just do this to check out "somefile.c" and have it overwrite any local, uncommitted changes:
# Check out "somefile.c" from `HEAD`, to overwrite any local, uncommitted
# changes
git checkout -- somefile.c
# Or check out a whole folder from `HEAD`:
git checkout -- some_directory
git checkout --
in my answer here: Who is "us" and who is "them" according to Git?.git checkout master -go to the master branch first
git checkout <your-branch> -- <your-file> --copy your file data from your branch.
git show <your-branch>:path/to/<your-file>
Hope this will help you. Please let me know If you have any query.
Supplemental to VonC's and chhh's answers.
git show experiment:path/to/relative/app.js > app.js
# If your current working directory is relative than just use
git show experiment:app.js > app.js
or
git checkout experiment -- app.js
This is a pragmatic approach which doesn't directly answer the OP, but some have found useful:
If the branch in question is on GitHub, then you can navigate to the desired branch and file using any of the many tools that GitHub offers, then click 'Raw' to view the plain text, and (optionally) copy and paste the text as desired.
I like this approach because it lets you look at the remote file in its entirety before pulling it to your local machine.
If you want the file from a particular commit (any branch) , say 06f8251f
git checkout 06f8251f path_to_file
for example , in windows:
git checkout 06f8251f C:\A\B\C\D\file.h
To restore a file from another branch, simply use the following command from your working branch:
git restore -s my-other-branch -- ./path/to/file
The -s
flag is short for source
i.e. the branch from where you want to pull the file.
(The chosen answer is very informative but also a bit overwhelming.)
Everything is much simpler, use git checkout for that.
Suppose you're on master
branch, to get app.js from new-feature
branch do:
git checkout new-feature path/to/app.js
// note that there is no leading slash in the path!
This will bring you the contents of the desired file. You can, as always, use part of sha1 instead of new-feature branch name to get the file as it was in that particular commit.
Note:new-feature
needs to be a local branch, not a remote one.
Another way is to create a patch with the differences and apply it in the master branch For instance. Let's say the last commit before you started working on app.js is 00000aaaaa and the commit containg the version you want is 00000bbbbb
The you run this on the experiment branch:
git diff 00000aaaaa 00000bbbbb app.js > ~/app_changes.git
This will create a file with all the differences between those two commits for app.js that you can apply wherever you want. You can keep that file anywhere outside the project
Then, in master you just run:
git apply ~/app_changes.git
now you are gonna see the changes in the projects as if you had made them manually.
git checkout branch_name file_name
Example:
git checkout master App.java
This will not work if your branch name has a period in it.
git checkout "fix.june" alive.html
error: pathspec 'fix.june' did not match any file(s) known to git.
Or if you want all the files from another branch:
git checkout <branch name> -- .
