#

#    modified: README

#    modified: lib/simplegit.rb

#

no changes added to commit (use “git add” and/or “git commit -a”)

stage一个文件，准备提交

$ git add README

$ git status

# On branch master

# Changes to be committed:

# (use “git reset HEAD <file>…” to unstage)

#

#    modified: README

#

# Changed but not updated:

提交刚才staged的文件

$ git commit -m ‘updated the README’

Stage另一个文件并且提交

$ git commit -a -m ‘added a staging command to the library’

$ git diff

diff –git a/lib/simplegit.rb b/lib/simplegit.rb
