bat echo 输出内容为不同的颜色 先看代码: @echo off SETLOCAL EnableDelayedExpansion for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do ( set "DEL=%%a" ) rem echo say the name of the colors,
bat echo 每行不同的颜色 先看代码: @echo off SETLOCAL EnableDelayedExpansion for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do ( set "DEL=%%a" ) rem echo say the name of the colors, don
echo的任务就是产生输出,可用来提示用户,或是用来产生数据供进一步处理. 原始的echo命令只会将参数打印到标准输出,参数之间以一个空格隔开,并以换行符号(newline)结尾. [many@avention my_sh]$ echo Now is the time for all good men Now is the time for all good men [many@avention my_sh]$
借助echo的-e选项来实现,语法格式为 echo -e "\033[3xmsome things you want to print out.\033[0m" \033[3xm为ANSI控制码,表示要开始输出有颜色的字符了. some things you want to print out.表示要输出的字符,和3xm紧挨着,如果中间有空格,输出的字符前面也会有空格. 3x为表示颜色的一组数字,x取值为0到7,分别代表的颜色如下: 30表示黑色. 31表示红色. 32表示绿色. 33
echo "Your error message here" >&2 This is a normal echo (which goes to stdout), however the >&2 (which is shorthand for 1>&2), means 'mix the stdout to the stderr'. 1 is stdout, and 2 is stderr here.
