ldap basics

aus https://de.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol:

" Ein einzelnes Objekt wird eindeutig durch den Distinguished Name (DN) identifiziert, wie zum Beispiel uid=juser,ou=People,ou=webdesign,c=de,o=acme. Dieser setzt sich aus einzelnen Relative Distinguished Names (RDN) zusammen. Eine andere Schreibweise für den DN ist der canonical name, der keine Attribut-Tags wie ou oder c enthält und bei dem die Trennung zwischen den RDNs durch Schrägstriche erfolgt. Außerdem beginnt die Reihenfolge, im Gegensatz zum dn, mit dem obersten Eintrag, also zum Beispiel acme/de/webdesign/People/juser."

git basics

basic workflow

Get bzw Checkout - from server to local repro

git config --list //list
  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

git clone https://github.com/username/reproname.git localDirName //get repro
git status //show changes
git log  //show last commits
git cherry -v //show commits needed to push

git fetch
git pull

anzeigen orgiginal url
git remote -v oder git config --get remote.origin.url.

push / checkin - from local to server

git add -A //stage changes

git commit -m "message"
ändern:
git commit --amend
git commit --amend -m "New commit message"
revert initial commit: git update-ref -d HEAD
git push

Revert

git checkout Dateiname

Stash

git stash list

git stash

git stash drop 1

Branches

switch to branch: git checkout branchname

https://git-scm.com/book/de/v1/Git-Branching-Einfaches-Branching-und-Merging

list all: git branch -a

list local: git branch -r

create: git branch myNewBranchName

merge:
git checkout destinationBranch (eg. master)
git merge branch (e.g. hotfix)

git branch -d hotfix //löschen

rebase:
git rebase -i HEAD~2

letzte 2 commits zusammenführen, es öffnet sich Editor, squash vor den commit schreiben den man "entfernen" will

Special

suda apt-get install git

git init --bare

git init

git remote -v

git remote add 

Git Atlassian Source Tree Basics

shows all commits in one timeline

get: clone / new (from server to local repro and files)
commit => files to local repro
push => from local repro to server
