实现代码：
#!/bin/sh # ANSI Color -- Use these variables to make output in different colors # and formats. Color names that end with 'f' are foreground (text) colors, # and those ending with 'b' are background colors. initializeANSI() { esc="33" # if this doesn't work, enter an ESC directly blackf="${esc}[30m"; redf="${esc}[31m"; greenf="${esc}[32m" yellowf="${esc}[33m" bluef="${esc}[34m"; purplef="${esc}[35m" cyanf="${esc}[36m"; whitef="${esc}[37m" blackb="${esc}[40m"; redb="${esc}[41m"; greenb="${esc}[42m" yellowb="${esc}[43m" blueb="${esc}[44m"; purpleb="${esc}[45m" cyanb="${esc}[46m"; whiteb="${esc}[47m" boldon="${esc}[1m"; boldoff="${esc}[22m" italicson="${esc}[3m"; italicsoff="${esc}[23m" ulon="${esc}[4m"; uloff="${esc}[24m" invon="${esc}[7m"; invoff="${esc}[27m" reset="${esc}[0m" }
先定义函数，接着初始化下函数，接着你就可以看到效果了。
执行
echo -e ${yellowf}This is a phrase in yellow${redb} and red${reset}
echo -e ${boldon}This is bold${ulon} this is italics${reset} bye bye
echo -e ${italicson}This is italics${italicsoff} and this is not
你了解了后以后及可以写出带颜色，很炫的脚本了
