Run E3SM

1) Fork a branch to my own repo on Github

2) Clone a branch from my own repository with submodules

$ git clone --recursive -b branch/name/here https://username:password@github.com/hydrotian/ACME.git

3) Make changes to the code, add them,and commit

$ git add --all
$ git commit –a -m "comments to this commit"

4) Push changes to my repo

$git push origin name/of/the/branch:name/of/the/branch

5) Send pull request on Github

Additional commands

check submodule list

$ git submodule if there are submodules, clone the submodules by

$ git submodule init
$ git submodule update

check remote and branch

$ git remote 
$ git branch -v

Add aliases

This following command create a “git hist” aliases based on “git log” to visually check the commit history

$ git config --global alias.hist "log --pretty=format:'%h %ad | %s%d [%an]' --graph --date=short"

Go back to old commits

find the hash of the target commit by checking the commit history, then

$ git checkout    # something like "git checkout 911e8c9"

Add ssh key to Github to avoid input password

  • Type cd ~/.ssh.
  • Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. If not, create them by typing
    ssh-keygen -t rsa -C "your_email@example.com"
    
  • Open id_rsa.pub, copy everything and paste it into GitHub and/or BitBucket under the Account Settings, SSH Keys

From old UW post

A great source: https://githowto.com/

1) On local machine, create an empty git repo in the working directory (e.g. project/) and set default setting:
$ git init

Check the current git settings:

$ git config –l

If no default git settings are set up yet:

$ git config --global user.name "Name"
$ git config --global user.email "Name@gmail.com"
2) Add all files to the local git repo and make the first commit:
$ git add --all`
$ git commit –a -m "First commit"
3) With any changes to the code, commit the changes
$ git commit -m "Changes are made to ……"
4) Create a bare repo outside of the working directory:
$ cd ..
$ git clone --bare project project.git
5) Push to my hydra directory
$ scp -r project.git/ tizhou@hydra:/git/tizhou
$ cd project
$ git remote add origin tizhou@hydra:/git/tizhou/project.git
$ git remote -v
7) If any future changes are made to the code in local directory project/, stage and commit the change:
$ git add –-all
$ git commit –a –m “Changes are made to …”
8) Push the change to hydra
$ git branch (Check the current working branch)`
$ git push –u origin master
