man ls 的结果
LS(1) LS(1)

NAME
ls, dir, vdir - 列目录内容

提要
ls [选项] [文件名...]

POSIX 标准选项: [-CFRacdilqrtu1]

GNU 选项 (短格式):
[-1abcdfgiklmnopqrstuxABCDFGLNQRSUX"] [-w cols] [-T cols] [-I pattern] [--full-time] [--format={long,verbose,com‐
mas,across,vertical,single-column}] [--sort={none,time,size,extension}] [--time={atime,access,use,ctime,status}]
[--color[={none,auto,always}]] [--help] [--version] [--]

描述（ DESCRIPTION ）
程序ls先列出非目录的文件项，然后是每一个目录中的
可显示文件。如果没有选项之外的参数【译注：即
文件名部分为空】出现，缺省为 "." （当前目录）。选
项 -d 使得目录与非目录项同样对待。除非 -a
选项出现，文件名以.开始的文件不属可显示文
件。

以当前目录为准，每一组文件（包括非目录文件项，以及
每一内含文件的目录）分别按文件名比较顺序排序。如果
-l 选项存在，每组文件前显示一摘要行给出该
组文件长度之和（以 512 字节为单位）。

输出是到标准输出（ stdout ）。除非以 -C 选项要
求按多列输出，输出将是一行一个。然而，输出到终端时，
单列输出或多列输出是不确定的。可以分别用选项 -1
或 -C 来强制按单列或多列输出。

-C 多列输出，纵向排序。
