简单汇总下git常见命令：

1. create your own folder

   mkdir aa
cd aa


   verify that the current folder is 「not」 tracked by Git:

   git status


2. create a new SAS program file

   echo "proc options; run;" > ./pgm/sas-git.sas


3. initialize a new repo by using the 「git init」 command

   git init --initial-branch==main


   This command creates a new git repository skeleton in a subdirectory named '.git' under the current directory. This meas that you're now able to start using other git commands in the current directory.

4. git configuration

   git config --list --show-origin | grep user


   or use this command in windows to check whether you set your name and email of github:

   git config --list --show-origin | findstr user


5. optional: set your basic identification configuration settings

   git config --global user.name "First-name Last-name"
git config --global user.email emailAddress@provider


6. stage your project files with the 「git add」 command

   git add .
git status


7. commit the files, we can use whether commit message (comment) we want

   git commit -m 'initial commit'


8. edit files, we can just use the ">>" to append something to the existing file's content

   echo "/* adding just a comment to the code */" >> ./pgm/sas-git.sas


9. stage and commit the files with this shortcut (-am means stage all and commit together)

   git commit -am "added a comment"


10. check repo history using the 「git log」 command

    git log --pretty=format:"%h %ae %s"


    the 「pretty」 option specifiers can make a more concise, readable history log with certain fields.

    or can use the 「--oneline」 option for a quick view:

    git log --oneline


11. push to a remote repository

    <!-- git remote add origin <remote_repo_url> --> #only do this once
git push -u origin main


12. pull from a remote repository

    git pull origin main
