How do I undo 'git add' before commit?

Answer 1

git reset filename.txt

Will remove a file named filename.txt from the current index, the "about to be committed" area, without changing anything else.

Answer 2

Run

git gui

and remove all the files manually or by selecting all of them and clicking on the unstage from commit button.

Answer 3

As per many of the other answers, you can use git reset

BUT:

I found this great little post that actually adds the Git command (well, an alias) for git unadd: see git unadd for details or..

Simply,

git config --global alias.unadd "reset HEAD"

Now you can

git unadd foo.txt bar.txt

Answer 4

Use git add -i to remove just-added files from your upcoming commit. Example:

Adding the file you didn't want:

$ git add foo
$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   foo
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
# [...]#

Going into interactive add to undo your add (the commands typed at git here are "r" (revert), "1" (first entry in the list revert shows), 'return' to drop out of revert mode, and "q" (quit):

$ git add -i
           staged     unstaged path
  1:        +1/-0      nothing foo

*** Commands ***
  1: [s]tatus     2: [u]pdate     3: [r]evert     4: [a]dd untracked
  5: [p]atch      6: [d]iff       7: [q]uit       8: [h]elp
What now> r
           staged     unstaged path
  1:        +1/-0      nothing [f]oo
Revert>> 1
           staged     unstaged path
* 1:        +1/-0      nothing [f]oo
Revert>> 
note: foo is untracked now.
reverted one path

*** Commands ***
  1: [s]tatus     2: [u]pdate     3: [r]evert     4: [a]dd untracked
  5: [p]atch      6: [d]iff       7: [q]uit       8: [h]elp
What now> q
Bye.
$

That's it! Here's your proof, showing that "foo" is back on the untracked list:

$ git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
# [...]
#       foo
nothing added to commit but untracked files present (use "git add" to track)
$

In Sourcetree you can do this easily via the GUI. You can check which command Sourcetree uses to unstage a file.

I created a new file and added it to Git. Then I unstaged it using the Sourcetree GUI. This is the result:

Unstaging files [08/12/15 10:43] git -c diff.mnemonicprefix=false -c core.quotepath=false -c credential.helper=sourcetree reset -q -- path/to/file/filename.java

Sourcetree uses reset to unstage new files.

Answer 6

Undo a file which has already been added is quite easy using Git. For resetting myfile.txt, which have already been added, use:

git reset HEAD myfile.txt

Explanation:

After you staged unwanted file(s), to undo, you can do git reset. Head is head of your file in the local and the last parameter is the name of your file.
