The git add command adds a specific (text.txt) file from  
  working directory to the staging area.

 The git status command displays the state of the working 
 directory and the staging area.

  For example If you have staged  the (text.txt)files with the 
  git add command that you later decide not to commit, you can 
  unstage these changes using this command.

  This command will not add a specific file but it will  add 
  all modified and untracked files to the staging area.

  content to a remote repository. Pushing is how you transfer 
  commits from your local repository to a remote repository.

  git log lists the commits made in the local repository.

  This command will display each commit on a single line.this 
  will be very useful for a project overview

  The git pull command is used to fetch and pull the 
  content from a remote repository to the local 
  repository.
