ls命令是Linux下最常见的命令之一。ls命令为英语单词list的缩写，正如英语单词list的意思，其基本功能是列出指定目录下的主要内容以及相关的属性信息。
默认状态下，ls命令会列出当前目录的內容。而带上基本参数后，大家可以用ls做更多的事情。做为最基础的同时又是使用频率很高的命令，大家很有必要弄清楚ls命令的使用方法，那么接下来一起看看吧！
语法格式: ls [选项] [文件]
-a | 显示所有文件及目录 (包括以“.”开头的隐藏文件)
-l | 使用长格式列出文件及目录信息
-r | 将文件以相反次序显示(默认依英文字母次序)
-t | 根据最后的修改时间排序
-A | 同 -a ，但不列出 “.” (当前目录) 及 “..” (父目录)
-R | 根据文件大小排序
-S | 递归列出所有子目录
-------------------------------------------------------------------
参考实例
列出所有文件(包括隐藏文件)：
[root@linuxcool ~]# ls -a
列出文件的详细信息：
[root@linuxcool ~]# ls -l
列出根目录(/)下的所有目录：
[root@linuxcool ~]# ls /
列出当前工作目录下所有名称是 “s” 开头的文件 :
[root@linuxcool ~]# ls -ltr s*
列出当前工作目录下所有名称是 “s” 开头的文件 :
[root@linuxcool ~]# ls -ltr s*
列出 /bin 目录下的所有目录及文件的详细信息 :
[root@linuxcool ~]# ls -lR /bin
列出当前工作目录下所有文件及目录并以文件的大小进行排序 :
[root@linuxcool ~]# ls -AS
