Overwrite single file in my current branch with the same file in the main branch?

Say I have two branches - master and redesign. How would I go about overwriting the file default.aspx.cs in my redesign branch with the one from master?

I found this question but it seems to go over how to revert a file back to it's previous version in the same branch. I also considered using a merge, but I don't want to merge, I want to overwrite. Suggestions?

Solution 1:

git checkout master path/to/default.aspx.cs

Before doing this, you probably have to : git checkout redesign

So, just git checkout FROM_BRANCH_NAME path/to/file

Solution 2:

To overwrite a file in a branch from another branch, i.e, master to redesign do (when redesign is the current branch)

git checkout master ./path_to_file/default.aspx.cs

git checkout branch_name ./path_to_file/file_name.[file_extension]
