不，我尝试构建功能
ESC_SEQ="\x1b["
# foreground red
FG_RED="${ESC_SEQ}31;"
# background yellow
BG_YELLOW="43;"
# style bold
FS_BOLD="1m"
# echo
echo -e "${FG_RED}${BG_YELLOW}${FS_BOLD}Hello World!"
答案 0 :(得分：1)
export ESC_SEQ="\e["
export YELLOW="43m"
function format_text()
{
BG="$ESC_SEQ$1"
echo -e "${BG}Hello World!"
}
format_text $YELLOW
我不知道如何在没有临时变量的情况下实现。所有examples我发现使用tmp变量来实现它。
答案 1 :(得分：1)
以下脚本应该是一个很好的起点：
#!/bin/bash
ext_echo()
{
declare -A colors
colors=(
[red]="<red>"
[blue]="<blue>"
)
for c in "$@"; do
echo ${colors[$c]}
done
}
ext_echo red blue
<强>输出
<red>
<blue>
