CompTIA Linux+ XK0-005 Practice Question

A system administrator is automating the backup process for a set of user directories. They have decided to write a shell script that compresses each user's home directory into an individual archive file. Assuming all user directories are located in /home, which snippet of code will successfully create a gzip-compressed archive of each user's home directory with the filename format 'username.tar.gz'?

for dir in /home/*/; do tar -cf "$dir" | gzip > "$.tar.gz"; done
for dir in /home/; do tar -czf "/home/${dir}.tar.gz" "/home/$"; done
for dir in /home/; do tar -czf "/home/${dir##/}.tar.gz" "$dir"; done
for dir in /home/; do gzip "/home/${dir##/}"; done

Report Issue

Answer Description

The correct script uses a 'for' loop to iterate over every item in the /home directory and then applies the 'tar' command with the correct options to compress each directory into an individual gzip archive file. The '${dir##*/}' expression is used to strip the path and leave just the user's name for the archive file. Incorrect answers may have syntax errors, use incorrect commands, or incorrectly handle the directory names, resulting in failure to achieve the desired task.
