ping(网络诊断工具)
ping是Windows、Unix和Linux系统下的一个命令
ping也属于一个通信协议，是TCP/IP协议的一部分
利用“ping”命令可以检查网络是否连通，可以很好地帮助我们分析和判定网络故障,用来作为可用性的检查
应用格式：ping空格IP地址 或者 ping空格域名
举例
C:\Users\xxx>ping baidu.comPinging baidu.com [123.125.115.110] with 32 bytes of data:Request timed out.Reply from 123.125.115.110: bytes=32 time=52ms TTL=49Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Reply from 123.125.115.110: bytes=32 time=52ms TTL=49Ping statistics for 123.125.115.110: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),Approximate round trip times in milli-seconds: Minimum = 51ms, Maximum = 52ms, Average = 51msC:\Users\xxx>ping 123.125.115.110Pinging 123.125.115.110 with 32 bytes of data:Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Request timed out.Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Ping statistics for 123.125.115.110: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),Approximate round trip times in milli-seconds: Minimum = 51ms, Maximum = 51ms, Average = 51ms原理：利用网络上机器IP地址的唯一性，给目标IP地址发送一个数据包，再要求对方返回一个同样大小的数据包来确定两台网络机器是否连接相通，时延是多少
ipconfig(查看本机ip)
举例
C:\Users\Administrator>ipconfigWindows IP ConfigurationEthernet adapter 以太网: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . :Ethernet adapter vEthernet (默认交换机): Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : xxxx::xxxx:xxxx:xxxx:xxxx IPv4 Address. . . . . . . . . . . : x.x.x.x Subnet Mask . . . . . . . . . . . : x.x.x.x Default Gateway . . . . . . . . . :Wireless LAN adapter 本地连接* 1: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . :Wireless LAN adapter 本地连接* 11: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . :Wireless LAN adapter WLAN: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : xxxx::xxxx:xxxx:xxxx:xxxx IPv4 Address. . . . . . . . . . . : x.x.x.x Subnet Mask . . . . . . . . . . . : x.x.x.x Default Gateway . . . . . . . . . : x.x.x.xEthernet adapter 蓝牙网络连接: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . :目录浏览
进入某个盘
D:目标盘:在当前盘中前进
cd 目标目录回退到上一级
cd..举例
C:\Users\Administrator>D:D:\>cd WeChatD:\WeChat>cdD:\WeChatD:\WeChat>cd..D:\>查看目录文件
dir如果是需要查看隐藏文件的或者更多操作的话，可以使用dir /?来查看其它用法
D:\WeChat>dir /?Displays a list of files and subdirectories in a directory.DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N] [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4] [drive:][path][filename] Specifies drive, directory, and/or files to list. /A Displays files with specified attributes. attributes D Directories R Read-only files H Hidden files A Files ready for archiving S System files I Not content indexed files L Reparse Points - Prefix meaning not /B Uses bare format (no heading information or summary). /C Display the thousand separator in file sizes. This is the default. Use /-C to disable display of separator. /D Same as wide but files are list sorted by column. /L Uses lowercase. /N New long list format where filenames are on the far right. /O List by files in sorted order. sortorder N By name (alphabetic) S By size (smallest first) E By extension (alphabetic) D By date/time (oldest first) G Group directories first - Prefix to reverse order /P Pauses after each screenful of information. /Q Display the owner of the file. /R Display alternate data streams of the file. /S Displays files in specified directory and all subdirectories. /T Controls which time field displayed or used for sortingPress any key to continue . . .清除屏幕
cls查看cmd下的命令
help找到命令之后，使用 命令+ /?来查看该命令下的其他属性
cd /?参考资料
