创建菜单
#!/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"

（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
