How to get just one file from another branch

Question

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

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.

Review the file on github and pull it from there  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

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
