簡單匯總下git常見命令：

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
