注：while循环用来不断重复菜单。当用户选择0以后就跳出循环。该模板适用于创建任何shell脚本界面。

使用select

#!/bin/sh

function whosen {

clear

who

}

function diskTB {

clear

df -k

}

function memusage {

clear

cat /proc/meminfo

}

ps3="enter option:"

select option in "display disk space" "display loging" "display memory usage" "exit program"

do

case $option in

"exit program")

break ;;

"display loging")

whosen ;;

"display disk space")

diskTB ;;

"display memory usage")

memusage ;;

*)

clear

echo "sorry wrong selecttion" ;;

esac

done
