1. Which option needs to be set to create a home directory for a new user using “useradd” command?

You simply just need to see the manual page of the useradd command.

man useradd

Look for anything that mention home directory…

And we got the answer!

Answer: -m

2. Which option needs to be set to lock a user account using the “usermod” command? (long version of the option)

Again, see the manual page of the usermod command.

man usermod

Look for something similar to ‘lock’.

And we got the answer!

Answer: --lock

3. Which option needs to be set to execute a command as a different user using the “su” command? (long version of the option)

Again, see the manual page of the su command.

man su

Look for anything related to command and different user. (nothing found)

When you want to run command as a different user, you are already doing a su which means ‘switch user’. The only thing we need to tell the CLI is we need to run a command.

So either we use -c or --command, but HTB required the long version of the flag.

Answer: --command
