I moved the thread to "UNIX for Beginners Questions & Answers" - and closed it. Please comply to the forum rules that you accepted when you registered: post homework / classwork in the home- and coursework forum respecting the home- and coursework rules.


Nevertheless, a few comments to your post:


  • A shell (and every other) variable has a value / contents that does not change depending on how it is used / evaluated. So $USER will show the same, be it echoed or printfed.
  • Urgent ("really need help") posts are deprected in here and don't get increased attention nor are they preferredly answered.
  • Heed what other, longer term members (here: bakunin) are suggesting on how to prepare a post so people ready to answer don't need to guess about what be the real problem.
