问题

平时用terminal的时候，偶尔会遇到这种有背景色的目录，这是因为该路径除了所有者外，还有其他人有权限。在有背景色的情况下，很容易与主题色发生冲突，导致看不清路径名称。修改方案除了调整路径的权限外，还有修改LS_COLORS环境变量。

$ echo $LS_COLORS
di=1;36:ln=35:so=32:pi=33:ex=31:bd=34;46:cd=34;43:su=30;41:sg=30;46:tw=30;42:ow=30;43

LS_COLORS环境变量由多个键值对用冒号连接而成，每个键值对的结构为key=val1;val2，不同值之间用分号连接。其中key为文件的类型缩写，value为对应的颜色编码

key	dir_colors name	description
no	NORMAL, NORM	Global default, although everything should be something
fi	FILE	Normal file
di	DIR	Directory
ln	SYMLINK, LINK, LNK	Symbolic link. If you set this to ’target’ instead of a numerical value, the colour is as for the file pointed to.
pi	FIFO, PIPE	Named pipe
do	DOOR	Door
bd	BLOCK, BLK	Block device
cd	CHAR, CHR	Character device
or	ORPHAN	Symbolic link pointing to a non-existent file
so	SOCK	Socket
su	SETUID	File that is setuid (u+s)
sg	SETGID	File that is setgid (g+s)
tw	STICKY_OTHER_WRITABLE	Directory that is sticky and other-writable (+t,o+w)
ow	OTHER_WRITABLE Directory	that is other-writable (o+w) and not sticky
st	STICKY	Directory with the sticky bit set (+t) and not other-writable
ex	EXEC	Executable file (i.e. has ‘x’ set in permissions)
mi	MISSING	Non-existent file pointed to by a symbolic link (visible when you type ls -l)
lc	LEFTCODE, LEFT	Opening terminal code
rc	RIGHTCODE, RIGHT	Closing terminal code
ec	ENDCODE, END	Non-filename text
*.extension		Every file using this extension e.g. *.jpg
