Introspect Git changes before you stage them

Using git add -p instead of git add can let you interactively introspect all the changes one at a time.

These are various things you can do with each hunk:

• y - stage this hunk
• n - do not stage this hunk
• q - quit; do not stage this hunk or any of the remaining ones
• 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
• ? - print help
