LFCS User and Group Management Practice Question
A temporary contractor 'contractor1' has left the company. The administrator needs to remove the user account and all associated files in the home directory. Which command accomplishes this?
⚠ Common exam trap
Test-takers frequently choose Option A, thinking `userdel` alone removes everything, or Option D, assuming `deluser` is universally available, when the LFCS exam tests the standard `userdel -r` command that works across all major Linux distributions.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
userdel -r contractor1
The `userdel -r contractor1` command removes the user account and, with the `-r` flag, also deletes the user's home directory and mail spool. This is the standard Linux command to completely remove a user and their associated files, as required by the scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
userdel contractor1
Why it's wrong here
userdel removes the account entry but leaves the home directory intact unless the -r flag is added, so contractor1's files would remain on disk. It is the right tool when the account should go while files are retained for auditing or transfer.
- ✗
passwd -d contractor1
Why it's wrong here
passwd -d deletes the account's password, leaving the account and its home directory fully present and loginable without authentication. It is used to blank a password for passwordless logins, not to remove a departing contractor's account or files.
- ✓
userdel -r contractor1
Why this is correct
`userdel -r contractor1` deletes the account and recursively removes the home directory with its mail spool, satisfying the requirement to erase all associated files. Plain `userdel` would leave `/home/contractor1` intact, so the `-r` flag is essential here.
- ✗
deluser --remove-home contractor1
Why it's wrong here
deluser --remove-home is Debian and Ubuntu specific; on RHEL-based systems the command does not exist, so it fails on the exam's target platform. It correctly deletes the account and home directory where the Debian toolset is installed.
