Command line basics

• This tutorial is taken from Corey schafer youtube video

• At first we need to configure the global configuration. That means who is working with the projects
• git config --global user.name "HasanGoni"
• git config --global user.email "hasanme1412@gmail.com"
• If we want to see all the configuration in this computer we can usually git config --list
• git help <verb>

  Two scenario to use git

• Local machine existing project you want to track it
• Existing project remotely you want develope.

1. Local project

Initializing the project

git init

• If we want to stop tracking the project we need to remove the .git directory. rm -r .git

Observe the status of the project

• git status to see the status of the project

Ignoring certain files

• To ignore some files need to add .gitignore file in the directory. vim .gitignore

• For example in python we don’t want to track pycache files. So we want to add .DS_Store in .project and *.pyc. Here we are saying please ignore .project directory and .DS_Store directory and ignore all files which ends with .pyc file extension.

Adding files

• We will add those lines to the .gitignore files and save them
• Adding files, we can just add all untracked files with git add -A
• Or we can just tell please add all the files. git add
• Or one can add just a single file like git add .gitignore. Here we just adding a single .gitignore file.

Remove files from staging area

• If we want to remove a file from staging area we can just say git reset <filename>. e.g. git reset .gitignore
• Like previously if we want everything to remove from staging area we can just say git reset

Commiting

git commit -m "Explanatory message of the change"

• if we want to see the status, we can use git log, which will show status and hashed history with commit message.

2. Track existing remote project with git

Clone remote repository

git clone <url> <where to clone>

• e.g. git clone ../remote_repo.git .. here . is current directory

Inoformation about remote repository

• git remote -v –list information of the repositroy
• git branch -a –> shows all the branches in the repository. Remote and local
• Now after doing some change we need to push it

  Show information of the changes done

  git diff git status shows what needs to be commited and what already commited

  Adding file

  git add -A adds to staging git status shows again the status. May be this time will show everything already commited because of previously git add

  Commit

  git commit -m "Information of the code"

• Now we want to push those changes to remote repository

  Pushing to remote repository

• First need to do git pull
• git push origin master –> origin is the name of the remote directory and master is the branch where we want to push

Common Workflow

• Create branch git branch new_branch
• Go to that branch git checkout new_branch
• Adding file git add -A
• Commit git commit -m "message Information"
• Pushing in Remote git push name_of remote_directory name_of_local_branch git push origin new_branch
• Show available branch git branch -a
• Checking out local master git checkout master git pull origin master
• Check which branches are merged git branch --merged
• Merging with master git merge new_brach when you are in master branch
• Push to remote brach git push oringin master
• Check again all the merges git branch --merged
• Delete new creeated branch git branch -d new_branch
• Delete branch from remote repository git push origin --delete new_branch
