如何“ls”仅一层深？

发布于 2024-10-16 01:02:52 字数 329 浏览 9 评论 0原文

我有很多包含数据的子目录，并且我想要一个我拥有的作业（子目录）的简短列表。我对以下命令不满意。

$ ls H2*
H2a:
energy.dat overlap.dat 
norm.dat zdip.dat ...
(much more)
H2b:
energy.dat overlap.dat
norm.dat zdip.dat ... 
(much more)

这种不必要的混乱违背了通配符的目的（限制输出）。如何将输出限制为一层深度？我想看到以下输出

H2a/ H2b/ H2z/

感谢您的帮助，缺口

原文

I have lots subdirectories containing data, and I want a short list of which jobs (subdirectories) I have. I'm not happy with the following command.

$ ls H2*
H2a:
energy.dat overlap.dat 
norm.dat zdip.dat ...
(much more)
H2b:
energy.dat overlap.dat
norm.dat zdip.dat ... 
(much more)

This needless clutter defeats the purpose of the wildcard (limiting the output). How can I limit the output to one level deep? I'd like to see the following output

H2a/ H2b/ H2z/

Thanks for your help,
Nick

试试这个

ls -d H2*/

-d 选项应该列出“仅目录”，但它本身只是列出

我个人觉得有点奇怪的。需要通配符才能获取实际的目录列表。

更新：正如@Philipp指出的，你可以更简洁地做到这一点，而无需离开bash，说

echo H2*/

差异在于ls将在单独的行上打印项目，这是通常对于通过管道传输到其他功能很有用。

Try this

ls -d H2*/

The -d option is supposed to list "directories only", but by itself just lists

which I personally find kind of strange. The wildcard is needed to get an actual list of directories.

UPDATE: As @Philipp points out, you can do this even more concisely and without leaving bash by saying

echo H2*/

The difference is that ls will print the items on separate lines, which is often useful for piping to other functions.

您应该考虑使用 find，如下所示：

find . -maxdepth 1 -type d -name "H2*"

注意：在“-max深度 1”之前放置“-type d”会导致 Debian Linux 上出现警告（“find：警告：您已在参数后指定了全局选项 -maxdepth”） -type，但全局选项不是位置性的，即 -max深度会影响在其之前指定的测试以及在其之后指定的测试。请在其他参数之前指定全局选项。”）Mac 上不会发出此类警告。

You should consider using find, like this:

find . -maxdepth 1 -type d -name "H2*"

NOTE: Putting "-type d" before "-maxdepth 1" results in a warning on Debian Linux ("find: warning: you have specified the global option -maxdepth after the argument -type, but global options are not positional, i.e., -maxdepth affects tests specified before it as well as those specified after it. Please specify global options before other arguments.") No such warning is issued on Mac.

echo H2*

由 Bash 进行扩展，因此您甚至不需要 ls。

如果您同时拥有以 H2 开头的文件和目录，则可以附加斜杠以将 glob 限制为目录：

echo H2*/

echo H2*

It's Bash who does the expansion, so you don't even need ls.

Should you have both files and directories starting with H2, you can append a slash to restrict the glob to directories:

echo H2*/

使用 Steve Baker 的 tree，网址为 http://mama.indstate.edu /用户/冰/树/
它填补了 ls 中缺少的许多内容。
要列出一层深的目录：

tree -adi -L 1 H2*

Use tree by Steve Baker at http://mama.indstate.edu/users/ice/tree/
It fills in for a lot of things that are missing from ls.
To list directories one layer deep:
