执行后，脚本将要求配色方案。配色方案以这种方式以文件为单位：

$ cat schemes
sch-001=red blue white
sch-002=green yellow black

相关的阵列在此处清楚地要求。此外，根据方案，应在另一个(nested)脚本或命令中使用每种颜色。在脚本中，应该像这样。

#!/usr/bin/env bash

... (The initial part of the script) ...

declare -A assscheme
mapfile -O 1 -t inscheme < schemes  #I prefer keys starting with 1

for val in "${inscheme[@]}"; do
   key=${val%%=*}
   value=${val#*=}
   assscheme[$key]=$value  
done

echo "${!assscheme[@]}"
echo "${assscheme[@]}"

read -p " Select color scheme: " color  #Let's say I've selected sch-001
echo "$color"

if [[ "$key" == "$color" ]] ; then


# I can't think of anything further yet.
#  And then I need something like this.

magick ......... -fill "$red" ...........
.........................................
script1 .......... -b "$blue" ...........
.........................................
script2 .......... -o "$white" ..........

fi

... (Continue the script) ...

如何以这种方式组织？还是还有另一种方式？

分析解答

一种选项可能是利用grep和cut将所选方案的颜色提取到数组中，然后访问颜色的单个数组元素。

#!/bin/bash

read -rp "Select color scheme: " scheme
printf "SCHEME: \n\t%s\nCOLORS: \n" "$scheme"

read -ra colors <<<"$(grep "$scheme" schemes.txt | cut -d= -f2)"
printf '\t%s\n' "${colors[@]}"

# Access the individual array elements as ${colors[0]}, ${colors[1]}, etc.
printf "First color: %s\n" "${colors[0]}"

例子：

$ ./script 
Select color scheme: sch-001
SCHEME: 
        sch-001
COLORS: 
        red
        blue
        white
First color: red
