Question

Say I have my own git repo with a bunch of text files in it. There is another different git repo that someone else owns with a bunch of text files that all differ from my ow

Answer 1

You can merge arbitrary files or repo objects. Simplest might be:

git merge-file file.txt <(git show last-merged-file.txt) /path/to/their/file.txt
# resolve any conflicts, then
git tag last-merged-file.txt `git hash-object-w file.txt`

Answer 2

Try to add the other-repo then bring its branches including your target-branch

git remote add other git@github.com:username/other-repo.git
git fetch other

Switch to the branch you want to merge in the target-file.ext:

git checkout your-branch

Merge the target file into yours:

git checkout -p other/target-branch target-file.ext

Answer 3

Go to your current directory, This way I'm doing currently, I hope you will help too.

cd your_current_git_Directory

Set your username and repository of another repository/second(from want to copy)

git remote add -f repo-b git@github.com:<username>/<repository>.git

Now, Merge the filename you looking for(if you want file merge subfolder)

git checkout -p repo-b/master  <folder_name>/<filename>

Or merge filename only

git checkout -p repo-b/master  <filename>

And Remove repository

git remote rm repo-b

Answer 4

If you are using any kind of packaging (artifacts) results in the original repo, then you can ask the owner of the repo to publish the sources as well. Then in your own repo you consume and unpack such artifact and just copy the file you need. E.g. If using Java-Maven, make sure the build on the original repo publishes also the sources, then in your own repo, you put a pre-step (before compile) in which you download the sources dependency, unpack the jar file and copy the one you need to your proper directory. There are maven plugins for that
