Why does egit give option to commit to head?

Question

When I commit a file using egit, what is the option available to select 'head'. Also, no files are commited when I select 'head'. Should I not be commiting to master only ?

Answer 1

You're clearly confusing committing and pushing. The screenshot you've shown is about setting up specification used for pushes. To understand what this dialog talks about, read the git-push manual, especially the bits dealing with the so-called "refspecs" as what that dialog supposedly is about is presenting you with a GUI interface for constructing a push refspec.
