Just a little cheatsheet… ;)

Start ssh-agent:

eval $( ssh-agent )
ssh-add /home/user/.ssh/id_ed25519_git
ssh -T [email protected]

Now you should be able to “git push”

New repository, using SSH:

git push origin master
git remote set-url origin [email protected]:username/repo.git
git remote add origin [email protected]:username/repo.git
git add .
git commit -m "First commit"

To change commit comment:

git commit --amend

 

---

 

Branches:

Clone the repository:

git clone

List all branches:

git branch -a

Checkout the branch that you want:

git checkout my-patch

Adding branches:

git branch
git checkout -b branchname
git push origin branchname
git remote add branchname [email protected]:username/repo.git
git commit .
git push branchname branchname

Switch between branches:

git checkout master
git checkout –

Remove remote (no really harmful):

git remote remove

More details about branches:

Update your branch when the original branch from official repository has been updated :

$ git fetch [name_of_your_remote]

Then you need to apply to merge changes, if your branch is derivated from develop you need to do :

$ git merge [name_of_your_remote]/develop

Delete a branch on your local filesystem :

$ git branch -d [name_of_your_new_branch]

To force the deletion of local branch on your filesystem :

$ git branch -D [name_of_your_new_branch]

Delete the branch on github :

$ git push origin :[name_of_your_new_branch]

Color:

git diff --color-words
git log --color-words
git show --color-words

 

Undo:

git checkout .  # revert your changes
git clean -fdxn # dry run
git clean -xdf  # delete untracked and ignored files (!!!)

 

SHA Hash:

git hash-object

(compare to:)
https://api.github.com/repos/user/repos/contents/file
https://api.github.com/repos/user/repos/bobs/hash

Removing sensitive data:

bfg --delete-files YOUR-FILE-WITH-SENSITIVE-DATA

bfg --replace-text passwords.txt

OR

git filter-branch --force --index-filter \
'git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA' \
--prune-empty --tag-name-filter cat -- --all

(add to .gitignore)

git push origin --force --all
git push origin --force --tags
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now

 

Working state:

Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory

git stash
git stash list
git stash show
git stash show -p --color

(!) remove all states:

git stash clear

 

List remote:

git ls-remote $URL

 

Versioning:

short commit hash:

git rev-parse --short HEAD

git describe --tags --always --dirty=-dirty

 

Logs:

git log --graph --abbrev-commit --format=format:'%h - %s%d'

git log --oneline 
git log --pretty=oneline --abbrev-commit

git log --abbrev-commit
git log -1 --abbrev-commit
git log -1 --pretty=format:%h
