控制输出颜色的shell脚本

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
