How to view the file size before I commit with git?

Question

I want to commit some files to GitHub, and I have created one ignore file, but how do I view the file size before committing?

Answer 1

Just a note on terminology - you record changes in a new "commit" locally (with git commit) and then would "push" your changes to GitHub. You only push commits, not particular files.

You've clarified in a comment that what you're after is the amount of data that would be uploaded when you do git push, in which case Jefromi's answer to the question Predict how much data will be pushed in a git push should help you.
