You want to switch to user admin and run two commands in sequence: whoami and pwd. Which command achieves this correctly?

Asu - admin -c 'whoami; pwd'

Bsu admin -c 'whoami && pwd'

Csu -c 'whoami; pwd' admin

Dsu admin 'whoami; pwd'

Step-by-Step Solution

Solution:

Step 1: Understand command chaining with su -c
The -c option runs the entire command string as the specified user.
Step 2: Verify correct syntax order
The syntax is su -c 'commands' username, so su -c 'whoami; pwd' admin is correct.
Step 3: Check command chaining
Using semicolon ; runs commands sequentially regardless of success.
Final Answer:
su -c 'whoami; pwd' admin -> Option C
Quick Check:
Multiple commands with su -c = single quoted string [OK]

Quick Trick: Put all commands in quotes after -c before username [OK]
