I find both of these can unstage a file.
I used to use git reset file
to unstage a file.
But today when I read the http://git-scm.com/book.
I find it taught me to use git reset HEAD file
, what does the HEAD do here? In which circumstances it's a must?
PS: An additional question, I can use git checkout file
to unmodified a file. Meanwhile this book suggest me to use git checkout -- file
. What's the difference here?
