Git  command line

Three  states

-     Working directory

-    staging area -  pre- commit holding area

-    Commit - git repository(history)

branch - time line of your changes

git version

git config --global user.name "your usernanme"

git config --global user.email "user@mail.com"

check configs

git config --global --list

Further you can check these in the file system in ".gitconfig" file inside user directory

eg: C:\Users\{username}\.gitconfig

It will contain something like below

--------------------------------------------------------------------------

[user]

name = Amal

email = aprasad@vsa.com

---------------------------------------------------------------------------

clone repository. create a folder to pull and execute clone command

git clone https://yourrepourl/demo.git

Now you have clone the repository.go to repository working directory and get status

git status

this will tell your branch and upto date status.

eg: 'origin\master' -  virtual reference to repository

This will check changes against

1. working directory

2. staging

3. local repository

4. remote repository

Note: working directory, staging, local repository are in Local and only remote repository lies outside.

Now add a new file "start.txt" for your working directory and see the status

it will show you that there is an untracked file

Remember file is still in "working directory"

you need to "add" to repository

git add start.txt

if you check "status' it will show you a new file: start.txt with the messaage "Changes to be committed. "

Now file is in "Staging" area.  Staging area let's keep multiple files and let you commit as a single unit.

Now you can commit using

git commit -m "your message to commit"

Now if you check status, git will tell - nothing to commit, working directory clean.

Now new file is moved from "staging area" to "Local repository" (.git folder)

we have still not pushed to Remote. if you go to remote repository via browser, you will see no changes.

git push origin master

origin - refers to the Github copy of your/our repository

master - refers to default and only branch

This will prompt for username and password

Now if you browse the Github repo , you will be able to see the newly pushed file.

Following commands may useful creating and go through files

pwd 

mkdir projects 

cd projects 

pwd
