#!/bin/bash
# testing the script
clear
echo
echo -e "\t\t\tSys Admin Menu\n"
echo -e "\t1.Display disk space"
echo -e "\t2.Display logged on users"
echo -e "\t3.Display memory usage"
echo -e "\t0.Exit menu\n\n"
echo -en "\t\tEnter option:"
（这段代码很有意思，会显示目录的效果）
创建菜单函数
function diskspace {
clear
df -k
}
function whoseon {
clear
who
}
function memusage {
clear
cat /proc/meminfo
}
添加菜单逻辑
case option in 0) break ;; 1) diskspace ;; 2) whoseon ;; 3) menusage ;; *) clear echo "Sorry,wrong selection" ;; esac 完整的菜单如下： #!/bin/bash # testing the script function diskspace { clear df -k } function whoseon { clear who } function memusage { clear cat /proc/meminfo } function menu { clear echo echo -e "\t\t\tSys Admin Menu\n" echo -e "\t1.Display disk space" echo -e "\t2.Display logged on users" echo -e "\t3.Display memory usage" echo -e "\t0.Exit menu\n\n" echo -en "\t\tEnter option:" read -n 1 option } while [ 1 ] do menu caseoption in

break ;;

echo -en "\n\n\t\tHit any key to continue"
read -n 1 line
