here's my rc script, no need for completion IMO when you can just type: 
`rc r l~pd` to restart lighttpd



if [ $# -ne 2 ]; then
     echo "usage: <OPERATION> <PATTERN>"
     echo "       OPERATION can also be one of: k(stop), r(restart), 
     echo "       PATTERN(grep -E ^PATTERN$) where $WC is replaced with .*"
     exit 1

case $1 in
k) opr="stop"
r) opr="restart"
s) opr="start"
*) opr=$1
if [ "$opr" = "" ]; then
     echo "error: no operation specified."
     exit 1

pat=$(echo $2 | sed "s/$WC/.*/g")
rc=$(ls /etc/rc.d/ | grep -E "^$pat$")
mat=$(echo $rc | wc -w)
if [ "$mat" = "1" ]; then
     sudo /etc/rc.d/$rc $opr
elif [ "$mat" = "0" ]; then
     echo "error: no targets found."
     echo "error: multiple targets found:"
     for t in $(echo $rc); do
         echo "       $t"
