title: How to use git pull to merge the remote branch into yours?
body: <p>Here i m successfully run git add and git commit on my gitlab account but when i perform git push they give me a following error:</p>
  
  <p>To gitlab.com:shrav/vaishaliAllProjects.git
   ! [rejected]        master -> master (fetch first)
  error: failed to push some refs to 'git@gitlab.com:shrav/vaishaliAllProjects.git'
  hint: Updates were rejected because the remote contains work that you do
  hint: not have locally. This is usually caused by another repository pushing
  hint: to the same ref. You may want to first integrate the remote changes
  hint: (e.g., 'git pull ...') before pushing again.
  hint: See the 'Note about fast-forwards' in 'git push --help' for details.</p>
  
  <p>Can anyone say how to perform git pull in ubuntu terminal??</p>
