            ^^^^^^^^

• Ignore Files and Folder, add

.gitignore

cat .gitignore

/debug

• Remove (before Commit)

git rm --cached README.md

• Add remote repo

git remote add origin https://server.com/repo.git
git add .

Commit

• Commit and write changes to editor

git commit 

• Be verbose

git commit -v

• Commit and write changes to oneline

git commit -m "message"

• Commit (without add) and write changes to oneline

git commit README.md -m "message"

• Amend to last comit

git commit --amend -m "amend"

Branches

• Add branch

git branch feature/new-table

• Add new branch and change into it

git checkout -b feature/new-table

• Change branch

git checkout feature/new-table

• Change branch

git switch main

• Delete Branch

git branch -d feature/new-table 

• Delete Remote Branch (with column)

git push origin :feature/docs-merge-request

• List branch

git branch

• List remote branch

git branch -r

• List local branch

git branch -v

• List connected branch

git branch -vv

Diff/Log/Show

• Diff

git diff
git diff --staged

• Log

git log
git log --oneline

• Show

git show <Commit ID>

• Blame (who)

git blame <file>

• Remote

git diff main remotes/origin/main

Merge

• Merge with rebase

git checkout -b feature1/new-table

• manage changes if conflicts

git rebase master
git checkout master

• merge

git merge feature1/new-table

• Merge with confilct

abort merge
git merge --abort

• Merge to master /fast forward) - no changes

git checkout master
git merge feature/new-table

• No fast forward

git merge feature/docs-hotfix --no-ff

• Gitlab - create project

git remote add origin git@gitlab.com:joexx/gittraining.git
git push origin master

• Get remote repo to local

git pull origin master

• Reset due to conflict (remote mor up to date than local)

git reset --hard origin/master
or (with a cleaner history)
git pull origin master --rebase

• Update local

git pull

• Rebase the last 3 commits (?)

git rebase -i HEAD~3

Practical Sample1

mkdir project
cd project
git clone ....
git checkout -b "New Branch"
#Make changes
git add *
git checkout -m "Your comment here"
git push --set-upstream origin "New Branch"

Tag

• Add Tag, do this after the commit

git tag v0.1
git tag
git push --tags

Working with remote repos

• get remote repo to local

git fetch

• get remote repo to local and commit

git pull

• Remote diff

git diff origin/main

• Rebase remote

git rebase origin/main
git rebase --continue

• Local to remote (default)

git push

• Push to specific remote branch

git push --set-upstream origin feature/docs-hotfix

• Pull repo and add a existing remote branch to the local branch

git clone git@ssh.server.com/repo.git
git switch branch-name
git pull

• If the above does not work, try

git clone git@ssh.server.com/repo.git
git checkout -b branch-name
git branch --set-upstream-to=origin/branch-name branch-name
git pull

Practical Sample2

mkdir project
cd project
git clone ....
git remote remove origin
git remote add origin git@.../.. .git
#Make changes
git add -A
git commit -m "initial project"
git push --set-upstream origin main
