git pull one file from remote

Question

I've cloned a repository "Rep" and created my own local branch "Li". I've committed a file called "task.js" to the local "Li" branch and pushed it to the remote "Li" branch. Now I want to revert this action by:

1. pulling the original "task.js" from the remote "master" branch to the local "Li" branch
2. push the reverted "task.js" from the local "Li" branch to the remote "Li" branch.

I tried to read several "pull" tutorials but can't figure out a way to do this (maybe because I don't really understand the basics yet...)

Thanks, Li

Solution

git reset HEAD~ will revert the laster commit of the current branch, but since you have already pushed the branch Li to public, it is better to do a git checkout master task.js and commit again in your branch Li.

Due to he his already pushed the Li branch which means this is probably not a good idea.

what does this command do? Does this overrides the local "Li" task.js with the local master task.js? (it worked, I just want to understand what I did)

[weynhamz]

Yes, git checkout master task.js will simply checkout the task.js of the master branch, for your case, you probably need a -f flag.

Oh, ok, so he need to revert that commit.
