1.判断/tmp/run目录是否存在，如果不存在就建立，如果存在就删除目录里所有文件

2.输入一个路径，判断路径是否存在，而且输出是文件还是目录，如果是链接文件，还得输出是有效的连接还是无效的连接 3.交互模式要求输入一个ip，然后脚本判断这个IP对应的主机是否能ping通，输出结果类似于： Server 10.1.1.20 is Down! 最后要求把结果邮件到本地管理员root@localhost mail01@localhost 4.判断用户输入的字符串，如果是"hello",则显示"world"；如果是"world", 则显示"hello"。 而脚本没有参数或者参数错误时，屏幕上输出 “usage:please input hello or world” 5.编辑一个脚本，实现自动搭建samba服务 #!/bin/bash echo -e “\033[32m#######judge the network!!!\033[0m” ping -c1 172.25.254.6 &>/dev/null if [ $? -eq 0 ] then echo “the network is ok” else echo “Error:the network is not working” exit 1 fi
