OS X：`ls` 可以显示损坏的符号链接吗？

Question

在 Linux 中，我喜欢用红色文本\ls -l --color=auto显示符号链接名称的损坏符号链接和丢失链接者的闪烁文本。但在 OS X 中，\ls -lG（我能找到的最接近的东西）显示损坏和未损坏的符号链接相同。

有谁知道如何让 OS Xls显示断开的符号链接与未断开的符号链接不同？它不必与 Linux 显示完全相同，而只是指示损坏状态的内容。

（如果重要，我也使用-A和-F选项。）

不幸的是，对于当前的 OSX (BSD)，ls这似乎是不可能的。参考手册页，这些是您唯一的选择：

LSCOLORS    The value of this variable describes what color to use for which
            attribute when colors are enabled with CLICOLOR.  This string is a
            concatenation of pairs of the format fb, where f is the foreground
            color and b is the background color.

            The color designators are as follows:
              a     black
              b     red
              c     green
              d     brown
              e     blue
              f     magenta
              g     cyan
              h     light grey
              A     bold black, usually shows up as dark grey
              B     bold red
              C     bold green
              D     bold brown, usually shows up as yellow
              E     bold blue
              F     bold magenta
              G     bold cyan
              H     bold light grey; looks like bright white
              x     default foreground or background

            Note that the above are standard ANSI colors.  The actual display may
            differ depending on the color capabilities of the terminal in use.

            The order of the attributes are as follows:
              1.   directory
              2.   symbolic link
              3.   socket
              4.   pipe
              5.   executable
              6.   block special
              7.   character special
              8.   executable with setuid bit set
              9.   executable with setgid bit set
              10.  directory writable to others, with sticky bit
              11.  directory writable to others, without sticky bit

            The default is "exfxcxdxbxegedabagacad", i.e. blue foreground and
            default background for regular directories, black foreground and
            red background for setuid executables, etc.

因此，除非有一些未公开的技巧来处理除此 10 个列表之外的其他文件类型，否则您最好的选择是安装GNU Coreutils，其中包含ls您熟悉的or orphan允许LSCOLORS环境变量中损坏的符号链接的颜色规范。
