Git for Dummies

what means what?

remote - remote means server like github, bitbucket
local - your repo stored in PC
remote repository - your repo available on github, bitbucket
origin - origin is remote from where you have did git clone
upstream - upstream is their main repo from which you have forked, useful to get latest changes from their repo.releases
tag - used for software releases
master - it's a branch named master (default created branch for new repo)
pull - get latest changes, remote branches and then move HEAD to latest commit (git pull = git fetch + git merge)
HEAD - head always refers to the latest commit on your current branch.
fetch - just download latest changes in separate path and do not integrate with your repo. git merge is required to integrate these changes

Stage & Commit

git add . (stage ALL new,modified files)

git add -A (stage ALL new,modified,deleted files)

git add file1.txt file2.txt file3.txt

git add -i (interactive add/revert)

git commit -m 'fixed this and that'

Git append (commit using last commit msg)

git commit --reuse-message=HEAD
_(make shortcut: add,append,push; run once in terminal)_
git config --global alias.append '!f() { git add -A && git commit --reuse-message=HEAD && git push; }; f' (run once)
git append (use it like this)

Git add+commit (1 line, if there's no new file created)

git commit -am "fixed this and that"

Git add+commit (1 line, add newly created files also)

git add -A ; git commit -m "Your Message" (powershell)
git add -A && git commit -m "Your Message" (bash)

Git add+commit+push (1 line, stage newly created files also, run it once to create alias in .gitconfig)

git config --global alias.lazy '!f() { git add -A && git commit -m "$@" && git push; }; f' (run once)
git lazy "fixed bugs" (use it like this)

Push/Pull (Get latest changes)

git push origin

git push upstream

git push upstream/some_branch

git push origin HEAD (push local changes to remote branch with same name)

git pull origin master (pull latest changes from remote master branch into local dev branch)

untrack & remove pushed files

add those to .gitignore
git rm -r --cached .
git add .
git commit -am "Remove ignored files"
git push

remove untracked files from local and server

(which persist even after adding to .gitignore)

git rm -r --cached . && git add . && git commit -am "Remove ignored files" && git push

Branch

create local branch (code will be copied from current branch ~master)
```
  git checkout -b feature_x
```
push newly created branch to remote (branch is not available to github.com unless you push it separately)
```
  git push --set-upstream origin feature_x
```

Add Remote branch (origin is your repo on github.com)

  git remote add origin https://github.com/user/repo.git

Add upstream (upstream is their main repo from which you have forked)
```
  git remote add upstream https://github.com/their_user/repo.git
```

Create new local version branch of an upstream branch

  git checkout -b feature_x upstream/master (master is the branch name)

Switch branch
```
  git checkout feature_x
```
delete the branch
```
git branch -d feature_x
```
show origin (repo/branch URL on github)
```
git remote show origin
```
change origin (link to different repo URL on github)
```
git remote set-url origin new.git.url
```
Clone uncommited changes to new branch make copy of changes in current A branch stack

git stash -u
git stash apply

carry these changes to new branch and do your work

git checkout -b new_branch

To see uncommited changes on previous A branch

git checkout A
git stash apply // or if you've made stash in some other branch: `git stash list` and then use correct number: `git stash apply 2`

Status of remote - local - origin branches tracking

git remote -v

  git branch -d feature_x

Status of remote - local - origin branches tracking

git remote -v

git remote show origin

git status

Create Pull Request

for can-menifest:

  hub pull-request -b release -r ankit-shukla

  hub pull-request -b pre-release -r ankit-shukla

for can-cntral:

  hub pull-request -b bixby-2 -r ankit-shukla

https://hub.github.com/hub-pull-request.1.html

Repo Status

git status

git add -i

show latest commits (to exit type q)
```
 git log
```
Display current branch
```
  git branch
```

Git GUI

use fork app on windows

Built-in git GUI

gitk

Git interactive commands

git add -i

use colorful git output

git config color.ui true

Resolve Merge Conflicts:

revert all our changes and pull latest from upstream (their repo):

  git reset --hard HEAD
  git pull -s recursive -X theirs upstream branch_remote

Revert last commit and keep the changes (local)

git reset HEAD^

Revert last remote commit (from remote, untracable)

git pull #to get that commit to local
git reset HEAD^ #remove commit locally
git push origin +HEAD #force-push the last HEAD commit to remote

Revert all local changes and local commits (local)

(fetch the latest history from the server and point your local master branch at it )

git fetch origin git reset --hard origin/master (master is the branch name)

Revert everything I did & make repo sync with upstream

git reset --hard upstream/master (master is the branch name)
git pull upstream master

Clean up a fork and restart it from the upstream

git reset --hard upstream/master (master is the branch name of original repo)
git push origin my_branch --force (or git push origin HEAD --force)

Git pull without committing local changes

hide your local uncommitted changes temporarily

  git stash --include-untracked // shorthand git stash -u

show all stashes
```
  git stash list
```

get latest changes
```
  git pull
```
now unhide your local uncommitted changes
(pop will restore only latest stash)
```
  git stash pop
```
or
```
git stash apply
```
git stash pop restore changes and also removes it from stack, git stash apply restores it but still keeps it on stack for possible later reuse (or you can then git stash drop it). So git stash pop is git stash apply && git stash drop

git Users

Set

git config --local user.name "localuser"
git config --local user.email "[email protected]"
git config --global user.name "globaluser"
git config --global user.email "[email protected]"

Get

git config --local user.name
git config --local user.email
git config --global user.name
git config --global user.email

git config --list

Remember Me

Remember username & password

1) Secured Way (Store globally)

    git config --global credential.helper manager //secured way for Windows

    git push http://example.com/repo.git
    Username: <type your username once>
    Password: <type your password once>

2) Unsecured way (Store globally)

    git config credential.helper store //username & password stored in plain-text in "%UserProfile%\.git-credentials"
    git push http://example.com/repo.git
    Username: <type your username once>
    Password: <type your password once>

3) Unsecured way (Store locally per repo)

    //saved in file 'cred' inside repo .git folder. Need to manually delete this file.
    git config credential.helper 'store --file=.git/cred'

4) Secured Way (Store in Cache)

    git config credential.helper 'cache --timeout=864000' // 10 days expiry
    git credential-cache exit // remove it from cache before timeout

Remove credentials

git config --unset credential.helper
git config --local --unset credential.helper
git config --global --unset credential.helper
git config --system --unset credential.helper
//Windows: delete from Control Panel\User Accounts\Credential Manager

Download big repository on poor bandwidth:

HTTPS Clone repo vs SSH Clone repo

HTTPS Clone - easier, works through firewalls & proxies, ask password everytime for push-pull (but password can be saved using git config credential.helper store)
SSH Clone - manually create SSH key & add it to github, password not required for push-pull. Remove key from github to revoke authorization for that PC.
