Step-by-Step Solution
Solution:

  1. Step 1: Silent input with prompt

    Use read -s -p "prompt" variable to hide input and show prompt.

  2. Step 2: Add echo for newline

    After silent input, add echo to move to a new line since input is hidden.

  3. Step 3: Compare inputs correctly

    Use [ "$pass1" = "$pass2" ] with quotes to avoid errors.

  4. Final Answer:

    read -s -p "Enter password: " pass1 echo read -s -p "Confirm password: " pass2 echo if [ "$pass1" = "$pass2" ]; then echo "Match"; else echo "Mismatch"; fi correctly implements all steps.

  5. Quick Check:

    Options B, C, and D have syntax errors or missing newlines. [OK]
Quick Trick: Use echo after silent read to add newline before next prompt [OK]
Common Mistakes:
MISTAKES
  • Missing echo after silent read causing prompt overlap
