file * | grep directory

输出(在我的机器上)——

[root@rhel6 ~]# file * | grep directory
mongo-example-master:    directory
nostarch:                directory
scriptzz:                directory
splunk:                  directory
testdir:                 directory

以上输出可以通过使用cut进行进一步细化:

file * | grep directory | cut -d':' -f1
mongo-example-master
nostarch
scriptzz
splunk
testdir

* could be replaced with any path that's permitted
 file - determine file type
 grep - searches for string named directory
 -d - to specify a field delimiter
 -f1 - denotes field 1

我用以下方法部分解决了这个问题:

cd "/path/to/pricipal/folder"

for i in $(ls -d .*/); do sudo ln -s "$PWD"/${i%%/} /home/inukaze/${i%%/}; done

    ln: «/home/inukaze/./.»: can't overwrite a directory
    ln: «/home/inukaze/../..»: can't overwrite a directory
    ln: accesing to «/home/inukaze/.config»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.disruptive»: too much symbolics links levels
    ln: accesing to «/home/inukaze/innovations»: too much symbolics links levels
    ln: accesing to «/home/inukaze/sarl»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.e_old»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.gnome2_private»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.gvfs»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.kde»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.local»: too much symbolics links levels
    ln: accesing to «/home/inukaze/.xVideoServiceThief»: too much symbolics links levels

好吧，这对我来说是主要的部分:)

再加上一个完整的循环，检索每个文件夹的路径，使用Albert的答案和Gordans的组合。这应该很有用。

for i in $(ls -d /pathto/parent/folder/*/); do echo ${i%%/}; done

输出:

/pathto/parent/folder/childfolder1/
/pathto/parent/folder/childfolder2/
/pathto/parent/folder/childfolder3/
/pathto/parent/folder/childfolder4/
/pathto/parent/folder/childfolder5/
/pathto/parent/folder/childfolder6/
/pathto/parent/folder/childfolder7/
/pathto/parent/folder/childfolder8/

仅列出目录:

ls -l | grep ^d

只列出文件:

ls -l | grep -v ^d 

或者你也可以这样做:

ls -ld */

一个当前目录的普通列表，它将是:

ls -1d */

如果你想要整理干净:

ls -1d */ | cut -c 1- | rev | cut -c 2- | rev | sort

记住:大写字符在排序中有不同的行为

我使用:

ls -d */ | cut -f1 -d'/'

这将创建一个没有结尾斜杠的单列——在脚本中很有用。
