learning git(1)

I stated learning ruby on rails .

Reference book (Rails 101)

First of all , I started to learn the basic operation of github (https://github.com/)

I learned from the website(http://try.github.io/levels/1/challenges/1)

Got 15 minutes and want to learn Git?

1.git init 

To initialize a Git repository

2.git status

see what the current state of our project is

3.git add filename

 add file to the staging area by using git add

4.git commit -m "註解"

To store our staged changes we run the commit command with a message describing what we've changed.

5.git add "*.txt" 

adding all changes

6.git log

look history

7.git remote add origin repository URL,

setting remote repository url(GitHub url by your account)

8.git push -u origin master

The name of our remote is origin and the default local branch name is master

The -u tells Git to remember the parameters, so that next time we can simply run git push and Git will know what to do.

9.git pull origin master

pull file from origin

10.git diff HEAD

look at what is different from our last commit by using the git diff command

HEAD :want the diff of our most recent commit

11.git diff --staged

run git diff with the --staged option to see the changes you just staged

12.git reset filename

You can unstage files by using the git reset command

13.git checkout -- <target>

Files can be changed back to how they were at the last commit by using the command

Restore the deleted files

14.git branch branchname

When developers are working on a feature or bug they'll often create a copy (aka. branch) of their code they can make separate commits to. Then when they're done they can merge this branch back into their main master branch.

15.git branch

you can see a main branch named master and your others branch named

16.git checkout branchname

You can switch branches using the git checkout <branch> command

17.git remove

remove all the things

18.git merge branchname

We're already on the master branch, so we just need to tell Git to merge the branchname branch into it:

19.git branch -d branchname

delete a branch.
