How to commit & push selected files but not all in Git

I have a git repo with two branches: develop and master. I work mostly at develop and when files are ready (sometimes not so sticky to this affirmation) I merge them to master branch to put them on production. Take a look to this pic:

enter image description here

All that files comes from develop branch and was merged but I only want to commit and push RepresentativeRestController.php but any time I do right click => commit all of them are included on the commit. How I get rid, temporary since they will be added later, of the ones I don't want to be included on the commit? I use Smartgit as a GUI client for Bitbucket repository. Any advice?

Solution

When you make a commit, all the staged file are included in the commit. If you wish to exclude certain files from a commit, unstage those files first.

I'm not sure how to do that with the Git UI you are using, but there should be a screen or something to manage which files with changes are staged and which aren't.
