Create a new repo from my local machine, it does not exist on github right now. we will create it, commit and push all the repo to the github account first write the command line:
> git init
write
> git status
you see will all the untracked files which is readme.md for now you have to stage all the untracked files by the command
> git add .
then write your first commit
> git commit -m "first commit from local repo"
lets push the committed files
> git push origin master
this will show an error because their is no such remote repo in the same name to push the files to, so we have to create an empty file in github and call it ' demo-repo2', then push the files to it using the following command
> git remote add origin https://github.com/Norhanms/demo-repo2.git
To show the repo changes write:
> git remote -v
Now you can push the files to the remote github repo
> git push -u origin master
this will create a branch called 'master' and push all the files to it.
From now you can write only
> git push
without the need to write origin master because when add the flag -u which means upstream which means push always to the same repo
To show all branches in the repo, type in the following command:
> git branch
To create a new branch, type in the following command:
> git checkout -b feature-readme-instructions
You are switched to work on this branch and if you showed all the existing branches, you will find that this branch is highlighted.
Type in git branch again to see.
To switch back to the master branch, type in:
> git checkout master
- create index.html file
Type the command git status to see all the modified and new files that need to be statged.
You will find index.html is untracked because it is new and the readme file is modified.
lets learn how to unstage the changes but first we need to stage them.
> git add .
To unstage write :
> git restore --staged .
Now lets enter to branch 'feature-readme-instructions'
> git checkout feature-readme-instructions
Write git status to check for the modified and new files that need to be staged
Stage and commit all the changes
> git add .
> git commit -m "updated the readme file with all the expliantion and add index.html"
Now try to push the new branch to github, lets write
> git push
It will raise an error, you have to define the branch as upstream to push files to
> git push --set-upstream origin feature-readme-instructions
or you can write for short '-u' instead of '--set-upstream'
Create a new branch and name it 'mytestbranch'
> git checkout -b mytestbranch
Modify the readme file, as I am writing now in it to explain the steps of deleting a branch, then stage and commit
> git add .
> git commit -m "update the readme"
Then push the new branch to github
> git push -u origin mytestbranch
Click on the green button 'compare and pull request' to merge the new branch with the master Write a comment and then click 'merge pull request'
Then to see the merged branch in the local master branch, you have to first change to the master branch and then pull the branch to it
> git checkout master
> git pull
> git branch -d mytestbranch
To unstage the changes
> git reset
To unstage and uncommit the last commit, HEAD~1 means go the commit one step further
> git reset HEAD~1
To see all the commits, type in
> git log
you can see all the commmit and each one has an id you can delete a commit by its id
> git reset id
