ls命令color设置

查看当前ls命令输出颜色设置

1
echo $LS_COLORS

方法一： 利用 $LS_COLORS 变量设置ls输出颜色

  1. 命令行执行 echo $LS_COLORS 了解当前颜色设置
  2. 在命令行中修改 $LS_COLORS 变量进行颜色调试
    export LS_COLORS=$LS_COLORS:"ow=34;41" , 修改的是other-writable目录的颜色设置
  3. 调试成功后，将设置写入 .bashrc

方法二： 利用 .dircolors 文件设置ls输出颜色

1
dircolors color-scheme-file

自定义ls输出颜色

1
dircolors -p > .dircolors

将当前颜色设置打印到.dirycolors文件。

修改.dircolors

在.bashrc 中执行dircolors ~/.dircolors，一般.bashrc都已经包含了如下设置：

if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
