BThe terminal shows an error message
CThe command auto-completes to <code>ls /usr/bin/</code>
DNothing happens
Step-by-Step Solution
Solution:

  1. Step 1: Understand double Tab behavior

    Pressing Tab twice quickly after a partial path tries to complete or list matches.

  2. Step 2: Check if only one match exists

    /usr/bin is the only directory starting with 'bi', so it auto-completes to that.

  3. Final Answer:

    The command auto-completes to ls /usr/bin/ -> Option C

  4. Quick Check:

    Single match + double Tab = Auto-complete [OK]
Quick Trick: Double Tab shows matches or completes if one match [OK]
Common Mistakes:
MISTAKES
  • Expecting error on double Tab
  • Thinking nothing happens
  • Assuming multiple matches exist
