Commit a file to a Different Branch Without Checkout

Question

Is it possible to commit a file in a git branch with out checking out that branch? If so how?

Essentially I want to be able to save a file in my github pages branch

Answer 1

This is how I do it:

if I've acidentally committed, roll back one commit:

git reset --soft 'HEAD^'

add the files you want to add

git add .

create a new temporary branch:

git checkout -b oops-temp

commit your changes:

git commit -m "message about this commit"

checkout the branch you meant to check out:

git checkout realbranch

merge the old branch:

git merge oops-temp

delete the old branch:

git branch -D oops-temp
