Bash 'quick help' function

Toward perfecting my laziness,

Add to bashrc:

function qh () (
    function qh1 () {
      out="$(help "$1" 2>&1 )"
      [ $? -ne 0 ] && return 1
      echo "$out"
    }

    type -all "$1" ; { qh1 "$1" || "$1" --help 2>/dev/null || man "$1" 2>/dev/null ;} | egrep -i -- "$2"
)

For quick help, run

qh foo bar

in order to search foo's help for bar. Equivalent to

foo --help | grep bar

.
