CompTIA Linux+ XK0-006 (V8) Practice Question

A Bash script is meant to run an rsync backup and then send an email report, but the script must always exit with the same status code that rsync produced, even though other commands run afterward. Which code fragment accomplishes this goal?

  • rsync -av /var/www/ backup:/var/www/ && \
    mail -s "Backup complete" [email protected] < /dev/null || \
    mail -s "Backup failed" [email protected] < /dev/null
    exit $?
    
  • set -e
    rsync -av /var/www/ backup:/var/www/ && \
    mail -s "Backup complete" [email protected] < /dev/null
    
  • rsync -av /var/www/ backup:/var/www/
    mail -s "Backup complete" [email protected] < /dev/null
    exit $?
    
  • rsync -av /var/www/ backup:/var/www/
    rc=$?
    mail -s "Backup complete" [email protected] < /dev/null
    exit $rc
