GitExperiment

Just for git practise create a new repository on the command line

echo "# GitExperiment" >> README.md
git init 
git add README.md 
git commit -m "first commit" 
git remote add origin https://github.com/taruncse/GitExperiment.git 
git push -u origin master 

• push an existing repository from the command line

git remote add origin https://github.com/taruncse/GitExperiment.git 
git push -u origin master

• Incase of Android studio command line if you writ only git commit and you want to exit from editor, then you have to follow the following steps,

  press "esc"(switch edit from insert mode) then ":" (Command mode) then "q" (quit command) then enter (as it is a VIM Editor)

• Create the branch on your local machine and switch in this branch :

  git checkout -b [name_of_your_new_branch]

• Only create a branch git branch branch_name

• Switch to a branch git checkout branch_name

• You can see all branches created by using git branch

• Update your branch when the original branch from official repository has been updated : git fetch [name_of_your_remote]

• To remove a file from git stage (if only a file then remove -r) git rm -r --cached <NAME_OF_THE_DIRECTORY>

• Change your remote's URL git remote set-url origin your_remote_url

• Verify that the remote URL has changed. git remote -v

• If you just inited it, you can just delete .git. rm -rf .git

• Add git tag on your last commit git tag -a GIVE_A_VERSION GIT_COMMIT_ID -m "Message here"

  Push a tag git push --tags origin master

  Show all tags git tag

  Delete tag from local git tag -d TAG_VERSION/ID

  OR tag --delete Tag_Name

  Delete tag from remote git push --delete origin tagName

• To unstage the file which is added by git add command

  git reset <filePath> (For a specific file)

  git reset (For all file)

• Checkout and create a branch from a existing tag:

  git checkout tags/<tag_name> -b <branch_name>

• Show all tags git tag Show all remote tags git ls-remote --tags origin

• Create tag git tag -a Tag_Name -m "Message"

• Push all tags git push --tags

• Remove git ignore cache. git rm -r --cached

• If you want to add your missing file with your last commit without modifying your commit message.
  git commit --amend --no-edit

• But if you want to change the commit message too.
  git commit --amend -m "New commit message"

• If you want to change the commit message manually.
  git commit --amend

• Tag using a specific commit id git tag -a Tag_name Tag_ID -m "Message here"

• Delete a local commit. (Here 1 is numbr of commit we want to delete)

  git reset --hard HEAD~1

• Ignore files that have already been committed to the repo

  git rm -r --cached .

  git add .

  git commit -m "Clean up ignored files"

• Delete a git commit but keep the changes

  git reset HEAD^

• Remove any versioned file from git track

  Firstly add that file to .gitignore file , then write following command

  Remove file from version controll

  git rm --cached -r fileNameWithExtension(Or Use dot(.) to remove all)
  
  

  git add .
  

  git commit -m "message"
  
  

• To get all the commit history

  git log
