Actually, find works on the system as my office:

# find -[tab]
-amin       -cnewer     -empty      -follow     -fstype     -ilname
 -iregex     -maxdepth   -mtime      -noleaf     -print      -regex
  -uid        -wholename
-anewer     -ctime      -exec       -fprint     -gid        -iname
 -links      -mindepth   -name       -nouser     -print0     -size
  -used       -xdev
-atime      -daystart   -false      -fprint0    -group      -inum
 -lname      -mmin       -newer      -ok         -printf     -true
  -user       -xtype
-cmin       -depth      -fls        -fprintf    -help       -ipath
 -ls         -mount      -nogroup    -perm       -prune      -type
  -version


The only big issue I've found with enabling command-completion is that
sometimes it seems to make the login process (SSH) take a second+
longer.
