运行Ruby脚本时更改bash终端输出颜色 [英] change bash terminal output color while running Ruby script

问题描述

我想简短地更改终端输出颜色，运行Ruby脚本，以便标准输出以更改后的颜色打印，睡眠"一秒钟，然后再将其更改回去.我知道如何设置颜色，就像提示一样:

I'd like to briefly change my terminal output color, run a Ruby script so that the stdout prints in that changed color, 'sleep' for a second, then change it back. I know how to set colors, like for the prompt:

PS1="\e[0;36m[\w] \e[m "

我想我需要编写一个bash函数来做到这一点.那会是什么样?

I imagine I need to write a bash function to do this. What would that look like?

推荐答案

这是一个红宝石脚本，用于显示所有终端颜色.下载或运行下面的代码.

Here is a ruby script to show all the terminal colors. Download it or run the code below.

def color(index)
  normal = "\e[#{index}m#{index}\e[0m"
  bold = "\e[#{index}m\e[1m#{index}\e[0m"
  "#{normal}  #{bold}  " 
end

8.times do|index| 
  line = color(index + 1)
  line += color(index + 30)
  line += color(index + 90)
  line += color(index + 40)
  line += color(index + 100)
  puts line
end
