Step-by-Step Solution
Solution:

  1. Step 1: Understand the error message

    The error says '-c' is unknown, which is not typical in Linux but common in Windows ping.

  2. Step 2: Identify environment mismatch

    Windows ping uses '-n' for count, so running Linux-style ping with '-c' in Windows causes this error.

    You are using a Windows command prompt instead of Linux terminal -> Option A

  4. Quick Check:

    Windows ping uses -n, Linux uses -c [OK]
Quick Trick: Windows ping uses -n, Linux uses -c [OK]
Common Mistakes:
  • Assuming domain name error
  • Thinking IP address is mandatory
