请问dearvoid，如何遍历当前目录下所有字目录？

复制内容到剪贴板

代码:

[color=blue]-(guest@mac:tty1)-(tmp)-
[5662 0] %[/color] cat foo.sh
#!/bin/bash

[ -L "$1" -o ! -d "$1" ] && exit 1

[color=red]pushd[/color] -n "$1" > /dev/null
while [color=red]dirs[/color] +1 > /dev/null 2>&1; do
    d_cur=$(dirs +1)
    [color=red]popd[/color] -n > /dev/null
    echo "$d_cur"
    for d in "$d_cur"/*; do
        [ -d "$d" -a ! -L "$d" ] && pushd -n "$d" > /dev/null
    done
done
[color=blue]-(guest@mac:tty1)-(tmp)-
[5662 0] %[/color] find a -type d
a
a/b
a/b/d
a/b/e
a/b/f
a/c

[color=blue]-(guest@mac:tty1)-(tmp)-
