inspired by the note taker, little todo script

todo() {
   test -f $HOME/.todo || touch $HOME/.todo
   if test $# = 0
   then 
           cat $HOME/.todo
   elif test $1 = -l
   then
           cat -n $HOME/.todo
   elif test $1 = -c
   then
           > $HOME/.todo
   elif test $1 = -r
   then
           cat -n $HOME/.todo
           echo -ne "----------------------------\nType a number to remove: "
           read NUMBER
           sed -ie ${NUMBER}d $HOME/.todo
   else
           echo $@ >> $HOME/.todo

       then

       elif [ $1 = -c ]
       then

Kingbash - menu driven auto-completion (see https://bbs.archlinux.org/viewtopic.php?id=101010)

install kingbash from aur then insert following in your .bashrc

function kingbash.fn() {
  echo -n "KingBash> $READLINE_LINE" #Where "KingBash> " looks best if it resembles your PS1, at least in length.
  OUTPUT=`/usr/bin/kingbash "$(compgen -ab -A function)"`
  READLINE_POINT=`echo "$OUTPUT" | tail -n 1`
  READLINE_LINE=`echo "$OUTPUT" | head -n -1`
  echo -ne "\r\e[2K"; }
bind -x '"\t":kingbash.fn'
