使用 ls 命令列出相同类型的文件可以产生具有不同颜色的文件

有人能解释一下为什么在列出某些具有相同扩展名的文件时，例如 .jpg 文件，为什么它们有时会显示为绿色，有时又会显示为粉红色。这些都是图像文件。这没有意义。

图像文件列表

答案1

该文件WhiterShadePale1.jpg具有执行权限。就这些。可执行文件的颜色会覆盖 *.jpg 颜色。

答案2

颜色由环境变量控制LS_COLORS。

手册ls页指出：

LS_COLORS       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 fore-
                ground and default background for regular directories,
                black foreground and red background for setuid executa-
                bles, etc.
