AWrong operator used for error redirection
BCommand does not produce errors
CMissing filename after redirection operator

    Missing filename after redirection operator -> Option C

  4. Quick Check:

    Filename required after 2>> = B [OK]
Quick Trick: Always specify a file after 2> or 2>> [OK]
Common Mistakes:
  • Leaving out filename after redirection
  • Assuming operator alone redirects errors
  • Confusing missing filename with wrong operator
