Git basic commands

1. Configure user information in git.

Git config -- global user. Name "Joey joejoe"

Git config-global user. Email "joey@joejoe.com"

 

2. initialize the project

The following operations are performed in the main directory of the project. The project files can be extracted from the tar.gz and ZIP files or created by yourself.

CD myproject/

Run the initialization command

Gitinit

Add all files in the current directory to git

Gitadd.

Submit update

Git commit

This will prompt you to write the submitted information, which is used to describe the content just submitted for future query. The initial commit can be written here.

Save and exit.

 

3. General Workflow

Generally, follow these steps:

A. Write or update the program in the project.

B. Check the changed files.

Git status

C. Check the actually changed files.

Git diff

D. Add the files or directories or other new files seen in B to the GIT repository.

Git add file1 newfile2newfolder3

E. Confirm submission,

Git commit

F enter the submission information. If the change is abandoned, exit the editor.

 

4. view the project status

View the current work

Git log

View the last three submissions

Git log-N3

Complete viewing

Git log -- stat -- Summary

 

5. View changes

View submitted updates

Git diff

View the ID of the change, for example

Git log-pretty = oneline

Bytes ---------------------------------------------------------------------------------------------------------------

The first 40 letters of each line are the updated idnumber. These numbers will also appear when git commit is executed. The difference between the two changes is that you need to use it. For example, when judging the differences between update point 1 and update Point 2:

Git diff 8fef .. c6e7

It can be seen that 40 letters do not need to be entered in all, but only the first few digits can mark an update point.

To view the last update point, you can use:

Git diff head ^ .. head

 

6. Fix errors

The changes have not been submitted and you do not want them. In this case, you can discard these changes:

Git reset -- hard

You can also perform such operations on a single file, but the commands are a bit different:

Git checkout myfile.txt

In the previous submission, I forgot to add some files. You can easily correct them:

Git reset-soft head ^

Git add forget.txt test.txt

Then submit.
