bash 使用 echo 为一个单词着色

Bash colour one word using echo

提问by Zippyduda

I am wanting to colourize one word in the middle of an echo sentence, but can't seem to achieve this.

我想为回声句子中间的一个词着色，但似乎无法实现这一点。

This works:

这有效：

#!/bin/bash
wipe="3[1m3[0m"
yellow='\E[1;33'
echo -e "$yellow"
echo Hello World
echo -e "$wipe"

But this doesn't:

但这不会：

#!/bin/bash
wipe="3[1m3[0m"
yellow='\E[1;33'
black="40m"
echo -e "Output a $yellow coloured $wipe word."
# or
echo -e "Output a ${yellow} coloured ${wipe} word."

What am I stupidly doing wrong? :)

我愚蠢地做错了什么？:)

You forgot an min your ANSI escape code for yellow. This works:

您m在 ANSI 转义码中忘记了yellow. 这有效：

yellow='\E[1;33m'

Much better, use tputto set a foreground colour:

更好的是，使用tput设置前景色：

textreset=$(tput sgr0) # reset the foreground colour
red=$(tput setaf 1)
yellow=$(tput setaf 2) 

echo "Output a ${yellow} coloured ${textreset} ${red} word ${textreset}."
