How to correctly save local changes in GIT?

Question

git

If I have a modified file then I just run the command.

git diff changet-file.txt > new-diff-file

And if in the future I need these changes, then git apply new-diff-fileto help.

But this method does not work with folders, and if there are a lot of files, you can simply get confused in them.

What methods or tools are there to effectively save local changes and then control them?

Answer 1

git checkout -b my_local_branch
git add .
git commit -m 'stub #100500'
git checkout master
