Basic Git commands
Here is a list of some basic Git commands to get you going with Git.

For more detail, check out the  Atlassian Git Tutorials  for a visual introduction to Git commands and workflows, including examples.
commands




Git task
Notes
Git commands




Tell Git who you are
Configure the author name and email address to be used with your commits.  
Note that Git strips some characters (for example trailing periods) from user.name
git config --global user.name “Sam Smith”   
git config --global user.email sam@example.com


Create a new local repository

git init


Check out a repository
Create a working copy of a local repository:
git clone /path/to/repository



For a remote server, use:
git clone username@host:/path/to/repository


Add files
Add one or more files to staging (index):
git add  ‘filename’ 
git add *


Commit
Commit changes to head (but not yet to the remote repository):
git commit -m ‘Commit message’



Commit any files you’ve added with git add, and also commit any files you’ve changed since then:
git commit -a


Push
Send changes to the master branch of your remote repository:
git push origin master


Status
List the files you’ve changed and those you still need to add or commit:
git status


Connect to a remote repository
If you haven’t connected your local repository to a remote server, add the server to be able to push to it:
git remote add origin ‘server’



List all currently configured remote repositories:
git remote -v


Branches
Create a new branch and switch to it:
git checkout -b ‘branchname’



Switch from one branch to another:
git checkout ‘branchname’



List all the branches in your repo, and also tell you what branch you’re currently in:
git branch



Delete the feature branch:
git branch -d ‘branchname’



Push the branch to your remote repository, so others can use it:
git push origin ‘branchname’



Push all branches to your remote repository:
git push --all origin



Delete a branch on your remote repository:
git push origin: ‘branchname’


Update from the remote repository
Fetch and merge changes on the remote server to your working directory:
git pull



To merge a different branch into your active branch:
git merge ‘branchname’



View all the merge conflicts: 
View the conflicts against the base file: 
Preview changes, before merging:
git diff 
git diff --base ‘filename’ 
git diff ‘sourcebranch’ ‘targetbranch’



After you have manually resolved any conflicts, you mark the changed file:
git add ‘filename’


Tags
You can use tagging to mark a significant changeset, such as a release:
git tag 1.0.0 ‘commitID’



CommitId is the leading characters of the changeset ID, up to 10, but must be unique. Get the ID using:
git log



Push all tags to remote repository:
git push --tags origin


Undo local changes
If you mess up, you can replace the changes in your working tree with the last content in head: Changes already added to the index, as well as new files, will be kept.
git checkout – ‘filename’



Instead, to drop all your local changes and commits, fetch the latest history from the server and point your local master branch at it, do this:
git fetch origin 
git reset --hard origin/master


Search
Search the working directory for foo():
git grep “foo()”

在Python 2中，经常使用commands模块来执行shell的命令，尤其是常用getstatusoutput()函数。
但是Python3中已经没有commands模块了，那么在Python 3中如果要调用一个命令，如何做呢？使用subprocess模块
import commands
import subprocess
shell_commands = 'sar 1 3|grep "^平均时间:"'
status,result = commands.getstatusoutput(shell_commands)
print(status,result)
-------->(0, '\xe5\xb9\xb3\xe5\x9d\x87\xe6\x97\xb6\xe9\x97\xb4:     all      3.42      0.00      1.49      0.00      0.00     95.10')
print(type(commands.getstatusoutput(shell_commands)))
-------->
print(result.split()[2:])   # 取得cpu各个指标的值
-------->['3.19', '0.00', '0.86', '0.09', '0.00', '95.87']
result = subprocess.Popen(shell_command,shell=True,stdout=subprocess.PIPE)
print(result)
-------->
print(result.stdout.read())
-------->平均时间:     all      3.05      0.00      0.85      0.00      0.00     96.10
print(type(result.stdout.read()))
-------->
print(result.stdout.read().split()[2:])   # 取得cpu各个指标的值
-------->['9.54', '0.00', '1.39', '0.17', '0.00', '88.90']

commands只能在linux下使用
#!/usr/bin/env python
#-*-coding:utf-8 -*-
import commands
cmd = 'ls /home/'
result = commands.getoutput(cmd)

print(type(result))
print (result)
#commands.getoutput的返回值只有返回结果，没法进行判断结果是否正常
cmd = 'ps -test'
status, result = commands.getstatusoutput(cmd)
print(type(result))
print(result)
print(type(status))
print(status)
#commands.getstatusoutput的返回值是一个tuple类型
#第一个值接受的状态码，返回结果是一个int类型，如果返回值是0，说明执行正常，如果非0，说明结果异常
#第二个值接受返回的结果，返回结果是一个str类型
