[Help-bash] distinguish local function and global function

[Peng Yu]

The following example shows that a local function can be defined
within a function. But `type` (as the way that I use it) cannot
distinguish them. Is there a way to tell what functions are local and
what are global?

$ cat main_x1.sh
#!/usr/bin/env bash
# vim: set noexpandtab tabstop=2:

set -v
function cmd {
function cmd1 {
    echo xxx
}
type cmd1
cmd1
}

type cmd
cmd
$ ./main_x1.sh
function cmd {
function cmd1 {
    echo xxx
}
type cmd1
cmd1
}

type cmd
cmd is a function
cmd ()
{
    function cmd1 ()
    {
        echo xxx
    };
    type cmd1;
    cmd1
}
cmd
cmd1 is a function
cmd1 ()
{
    echo xxx
}
xxx
