fi

fn=nv.shada
dir=$PWD
curdir=$PWD

while true
do
    path=$dir/$fn
    if [ -e $path ]
    then
        # open old shada in parent directory
        break
    fi
    if [ "$dir" == "/" ] || [ "$dir" == "$HOME" ] || [ "$usecurdir" == 1 ]
    then
        # create new shada in current directory
        path=$curdir/$fn
        touch $path
        break
    fi
    # try parent directory
    dir=$(dirname $dir)
