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
6) Link local and hydra repos, and check the remote connections
$ 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
Additional examples
- Clone a branch by providing the username and password in the same line
$ git clone -b branch/name/here https://username:password@github.com/ACME-Climate/ACME.git
check submodule list
$ git submodule
if there are submodules, clone the submodules by
$ git submodule init
$ git submodule update
Or, from git clone, add --recursive operation will automatically update the submodules
- Add aliases
This following command create a git hist aliases to 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"
- Revert the commit that already pushed to remote
- make sure you are on the branch head
- move the head one step backward
$ git reset --hard HEAD~1 - do some modifications and commit
- push the new commit to the origin
$ git push origin --force
