The command "lastlog -time ${3}" is used to display the most recent login activity for a system user. Here is its breakdown:
- "lastlog" is the actual command being invoked.
- "-time" is an option that is used to sort the output based on the last login time.
- "${3}" is a placeholder for a variable. The value of the variable is typically provided as a command-line argument when running the script.
So essentially, this command will retrieve and display the last login time and details for a specific user specified by the value of "${3}".
