Useful completion function if you have sudo to a number of users with a small number of commands.

<geshi lang="bash"> _sudo() {

 local cur prev opts base
 COMPREPLY=()
 cur="${COMP_WORDS[COMP_CWORD]}"
 prev="${COMP_WORDS[COMP_CWORD-1]}"

 case "${prev}" in
   -u)
     COMPREPLY=( $(compgen -W "$(sudo -l |  grep "^    " | cut -c6-13 | sort | uniq )" -- ${cur}) )
     return 0;
     ;;
   *)
   ;;
 esac
 if [ $COMP_CWORD -eq 3 ]; then
   COMPREPLY=( $(compgen -W "$(sudo -l | grep "\(${prev}\)" | cut -c16- | tr ',' ' ' )" -- ${cur}) )
   return 0;
