rm: illegal option -- x

I have a machine dedicated to building packages that has the following in root's crontab:
Code: 
43 5 * * 0-2,4-6 /usr/sbin/pkg upgrade -y && /usr/local/bin/poudriere ports -u -p local && /usr/local/bin/poudriere bulk -j 9buildi386 -p local -z xxxxx -f /usr/local/etc/poudriere.d/9buildi386-local-xxxxx-pkglist && /home/xxxx/FileProc/checkshut

/home/xxxx/FileProc/checkshut is a script which does:
Code: 
#!/usr/local/bin/bash
# checkshut - checks no VMs running, user xxxx not logged on and shuts down

while [[ `su - xxxx -c 'VBoxManage list runningvms'` ]]
do
  sleep 120
done

if ! users | grep -q xxxx ; then
  /sbin/shutdown -p +1
fi

This morning I found the machine still running and an e-mail in root's mailbox ending:
Code:

  unlink file

I have checked /usr/local/bin/poudriere for any rm commands and the string "Unmounting" but neither seems to be there, and I seem to recall "Umounting file systems" as a message from /sbin/shutdown, but why would it call rm with an illegal option?

This is most odd. Any ideas?
 
Possibly it's not rm but unlink that is being called. They are the same command but take different arguments, and unlink takes no options. Probably a part of poudriere cleanup.

I would avoid bash for shell scripts, but maybe that's just me.
