Git文件状态描述

检查当前文件状态

[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
nothing to commit (working directory clean)

说明当前git目录很干净，所有已跟踪的文件在上次提交后没有修改过。当前的分支为master

Untracked状态

touch创建一个README文件后

[root@typhoeus79 ice_test_m git_test]# touch README
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       README
nothing added to commit but untracked files present (use "git add" to track)

出现Untracked状态，说明有git在之前的提交中没有这些文件。

NewFile状态

使用git add跟踪这个文件

[root@typhoeus79 ice_test_m git_test]# git add README
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   README
#

在 “Changes to be committed” 这行下面的，就说明是已暂存状态。

git add 的潜台词就是把目标文件快照放入暂存区域，也就是 add file into staged area，同时未曾跟踪过的文件标记为需要跟踪。

modified状态

编辑README文件，写入新内容

[root@typhoeus79 ice_test_m git_test]# echo 11 >README
[root@typhoeus79 ice_test_m git_test]# cat README
11
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   README
#
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   README
#

出现在 “Changes not staged for commit” 这行下面，说明已跟踪文件的内容发生了变化，但还没有放到暂存区。要暂存这次更新，需要运行 git add 命令

再次运行git add之后，状态如下：

[root@typhoeus79 ice_test_m git_test]# git add README
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   README
#

Commit操作-提交更新

[root@typhoeus79 ice_test_m git_test]# git push
Everything up-to-date
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   README
#

紧接着直接push的话，会出现“Everything up-to-date”，但是查看git status，README还一个新文件，只是被commited而已

需要执行一次commit

[root@typhoeus79 ice_test_m git_test]# git add README
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       new file:   README
#
[root@typhoeus79 ice_test_m git_test]# git commit -m "commit"
[master 0ec3465] commit
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 README
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
nothing to commit (working directory clean)

当前工作环境已经clean，branch方式有1个commit

Push操作-推送到远程仓库上

[root@typhoeus79 ice_test_m git_test]# git push
Counting objects: 4, done.
Writing objects: 100% (3/3), 234 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)

   ecc80ec..0ec3465  master -> master
[root@typhoeus79 ice_test_m git_test]# git status
# On branch master
nothing to commit (working directory clean)

上面的1个commit已经没有，回到初始的状态
