该命令列出当前路径下的目录:
ls -d */
模式*/到底做什么?
我们如何在上面的命令中给出绝对路径(例如ls -d /home/alice/Documents)，只列出该路径下的目录?
当前回答
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:)
其他回答
如果你想知道为什么'ls -d */'的输出会给你两个斜杠，比如:
[prompt]$ ls -d */
app// cgi-bin// lib// pub//
这可能是因为您的shell或会话配置文件将ls命令别名为包含-F标志的ls版本。该标志将一个字符附加到每个输出名称(这不是普通文件)，表明它是什么类型的文件。因此，一个斜杠来自匹配模式'*/'，另一个斜杠是附加的类型指示符。
要解决这个问题，当然可以为ls定义一个不同的别名。然而，为了暂时不调用别名，你可以在命令前加上反斜杠:
\ls -d */

使用Test -d测试项目是否为目录:
for i in $(ls); do test -d $i && echo $i ; done
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
对于所有没有子文件夹的文件夹:
find /home/alice/Documents -maxdepth 1 -type d
对于所有带子文件夹的文件夹:
find /home/alice/Documents -type d
