Git: How to update/checkout a single file from remote origin master?

问题

The scenario:

1. I make some changes in a single file locally and run git add, git commit and git push
2. The file is pushed to the remote origin master repository
3. I have another local repository that is deployed via Capistrano with the "remote_cache" method from that remote repository
4. Now I don't want to deploy the whole application but just update/checkout that single file.

Please, is this somehow possible with git? I wasn't able to find anything that would work nor was I able to figure it out. With SVN I just did svn up file and voila.

I'll be glad for any help, thanks!

回答1:

It is possible to do (in the deployed repository)

git fetch
git checkout origin/master -- path/to/file

The fetch will download all the recent changes, but it will not put it in your current checked out code (working area).

The checkout will update the working tree with the particular file from the downloaded changes (origin/master).

At least this works for me for those little small typo fixes, where it feels weird to create a branch etc just to change one word in a file.

Following code worked for me:

     git fetch
     git checkout <branch from which file needs to be fetched> <filepath> 

回答3:

git archive --format=zip --remote=ssh://<user>@<host>/repos/<repo name> <tag or HEAD> <filename> > <output file name>.zip

What you can do is:

1. Update your local git repo:

   git fetch

2. Build a local branch and checkout on it:

   git branch pouet && git checkout pouet

3. Apply the commit you want on this branch:

   git cherry-pick abcdefabcdef

   (abcdefabcdef is the sha1 of the commit you want to apply)

With Git 2.23 (August 2019) and the new (still experimental) command git restore, seen in "How to reset all files from working directory but not from staging area?", that would be:

git fetch
git restore -s origin/master -- path/to/file

The idea is: git restore only deals with files, not files and branches as git checkout does.
See "Confused by git checkout": that is where git switch comes in)

回答6:

Or git stash (if you have changes) on the branch you're on, checkout master, pull for the latest changes, grab that file to your desktop (or the entire app). Checkout the branch you were on. Git stash apply back to the state you were at, then fix the changes manually or drag it replacing the file.

This way is not sooooo cool but it def works if you guys can't figure anything else out.

回答7:

I think I have found an easy hack out.

Delete the file that you have on the local repository (the file that you want updated from the latest commit in the remote server)

And then do a git pull

Because the file is deleted, there will be no conflict
