committing only some changes to git

git add -p <filename>
//git will begin to break down your file into what it thinks are sensible "hunks" (portions of the file). It will then prompt you with this question:
// OUTPUT >>> Stage this hunk [y,n,q,a,d,/,j,J,g,s,e,?]?
/*
Here is a description of each option:

	y stage this hunk for the next commit
	n do not stage this hunk for the next commit
	q quit; do not stage this hunk or any of the remaining hunks
	a stage this hunk and all later hunks in the file
	d do not stage this hunk or any of the later hunks in the file
	g select a hunk to go to
	/ search for a hunk matching the given regex
	j leave this hunk undecided, see next undecided hunk
	J leave this hunk undecided, see next hunk
	k leave this hunk undecided, see previous undecided hunk
	K leave this hunk undecided, see previous hunk
	s split the current hunk into smaller hunks
	e manually edit the current hunk
		You can then edit the hunk manually by replacing +/- by # (thanks veksen)
	? print hunk help

If the file is not in the repository yet, you can first do git add -N <filename>.
Afterwards you can go on with git add -p <filename>.

Afterwards, you can use:

	git diff --staged to check that you staged the correct changes
	git reset -p to unstage mistakenly added hunks
	git commit -v to view your commit while you edit the commit message.

//Note this is far different than the git format-patch command, whose purpose is to parse commit data into a .patch files.
