this is a dummy app for git tutorial

also see https://guides.github.com/features/mastering-markdown/ for markdown guide.

download git from www.git-scm.com and gitbash is the terminal i used here.

configure your username and email so your uploads are marked with your name and email. (optional probably)

• git config --global user.name "Pushkar Shrivastava"
• git config --global user.email "[email protected]"

• git init initialize local git repository.

• git add [file] add file(s) To index,or to staging, or to be tracked by git. ```git does not track you files unless you instruct git to do so. After files are tracked/staged/indexed, you can go further.

• git add * .[html] to add all files with html extension to staging or be tracked by git.

• git add . or git add --a to add all files for staging.

• git rm --cached [file name] to remove a file from staging area.

• git status check status of working tree.

• git diff to see the differences between your staged and unstaged/modified file(s).

• git diff --staged to see differences in every previous stages.

• git reset this will unstage all the staged/tracked files.

• for security plz add ssh. reference = "https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent" , "https://devmarketer.io/learn/set-ssh-key-github/"

• for ssh

• ssh-keygen -t rsa -b 4096 -C "[email protected]" -t = type,-b = byte size, -C = label, It will asks you a few things like what should be the file name in which you want to save the shh key. I use multiple files for multiple accounts, each for each github account.

• eval `ssh-agent -s` to start ssh agent

• ssh-add ~/.ssh/id_rsa this add/register the generated ssh to ssh agent

• clip < ~/.ssh/id_rsa.pub to copy ssh text to clipboard

• next part of ssh is on reference = "https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent" , "https://devmarketer.io/learn/set-ssh-key-github/"

• git commit -m "commit message" to commit with a message.

• git commit -a -m "Direct commit" commit files directly,from tracked state. and skip the staging phase.

• git rm "file name" or git mv "file name" "new file name" to change file names ``` having a git keyword before these type of command auto stages the output of command.

• upon adding a file to .gitignore,you should also run git rm --cached [file name] command to untrack those ignored files from git.

• git remote add origin https:github.com/USERNAME/REPOSITORY.git to add a remote connection for your project folder to another folder on github.

• git remote set-url origin https://github.com/USERNAME/REPOSITORY.git to update an existing link.

• git remote rm origin to remove a link completely,it works only at local pc not on remote.

• git remote to see all remote connections existing.

• git push -u origin master to upload your project to github folder. with master as a branch.

• git push origin [branch name] this will create a new branch of your branch name at remote repository and push the code.

• git push origin [branch name]:[branch name at remote] this will create a new branch at remote repository with specified name and push the code.

• git clone [github link] to download a git project.

• git pull to download an upto-date version of github project.

• git log this command gives a brief info of all commits done on your project.

• git log -p it also tell what is being removed and add in your log info.

• git log -p -[number] gives only the number of commit as you specified.

• git log --stat give slightly less breif info of commit.

• git log --pretty=[oneline],[short],[full] another way to represent your commit logs.

• git checkout --[file name] to bring you file state back to prevoius commit state.

• git checkout -f to bring you project state back to prevoius commit state.

• git config --global alias.[alias name] '[your command you want to have an alias for]' this way we can give a short name for a command in git so when we write the short name,its corresponding command is used by git.

• git clone clone Repository into a new directory.

• git pull pull latest version of repo from remote repository.

• rm -rf .git this will remove your .git folder and end all git services to your project.

• if you delete something on your project and want to move to previous state,use :-

• git fetch origin master

• git reset --hard FETCH_HEAD

• create a file with touch [file name].

• add a file name inside .gitignore to ignore the specified file being accessed by git.

• git branch to see all branches you have.

• git branch [branch name] to add a branch to your project.while you are in a branch,you cannot see any file created in other branches. this command does not execute if you have just initialized git and haven't added and performed your first commit.

• git checkout [branch name] to switch to the specified branch...by defaulf all projects have a master branch.

• git merge [branch name] to merge a specified branch to the master branch.first switch to the master branch then use merge command.

• git branch --merged to see merged branches.

• git branch --no-merge to see branches which are not merged.

• git branch -d [branch name] to delete a specified branch. git will give a warning message if the branch is not merged to master and ask you to rewrite command with a capital D again.
