jonadab,
Depending on how forgiving and user friendly smackdab wants to be, your solution can be improved:
  • Pass raw data to parsing sub
  • If match found, execute accordingly
  • If match not found, give user a list of currently supported commands

    The parsing sub may do things like:

  • Force lower case
  • Change (un)?lock user (un)?lock_user
  • Allow synonyms such as halt for shutdown
  • Regular expressions to handle common typos
  • Append non matches to a log for further analysis to help improve parsing routine

    The only other thing that I would suggest is changing the key assignment from anonymous subs to named subs. 

    shutdown => sub { print "Shutting down...\n"; exit 0; }

becomes

shutdown => \&shutdown
