A bash script to mess with the containing Terminal.app window

I found it, but I still don’t have a clue as to why I wrote it to begin with:

function setgeometry
{
    local rows=`expr "$1" : '[0-9]*x([0-9]*)$'`
    local cols=`expr "$1" : '([0-9]*)x[0-9]*$'`
    case $TERM in
        Apple_Terminal)
            window=`osascript -e 'tell app "Terminal" to get first window'`
            #echo $window
            osascript -e 'tell app "Terminal"'
                             -e "set number of rows of $window to $rows"
                             -e "set number of columns of $window to $cols"
                         -e 'end tell'
            return $?
            ;;
        *)
            echo "Sorry, I don't know how to do that in $TERM"
            return 1
            ;;
    esac
}

{: lang=bash }

It doesn’t seem to work anymore, but the concept is still valid (i.e., osascript -e 'tell app "Terminal"' -e 'set blib to first window' -e "get blib's number of columns" -e 'end tell' will actually tell you something, although that’s hardly a useful example).
