当使用"add"或者"del"参数时,路由表被修改,如果没有参数,则显示路由表当前的内容。 Linux系统的route命令用于显示和操作IP路由表(show / manipulate the IP routing table)。要实现两个不同的子网之间的通信,需要一台连接两个网络的路由器,或者同时位于两个网络的网关来实现。在Linux系统中,设置路由通常是为了解决...

help output will show the +|-M option. -n inhibits the conversion of network numbers to host names for network files. Inhibiting conversion may make lsof run faster. It is also useful when host name lookup is not working properly. -N selects the listing of NFS files. -o directs lsof ...
The lsof utility can help identify which files are being used by any given application, which network ports are open, and much more. A process would show up in top or ps aux, but the executable may not seem to exist. Using lsof, we could hunt down the scripts or executables used to ...

lsof(list open files)是一个列出当前系统打开文件的工具。在linux环境下,任何事物都以文件的形式存在,通过文件不仅仅可以访问常规数据,还可以访问网络连接和硬件。所以如传输控制协议 (TCP) 和用户数据报协议 (UDP) 套接字等,系统在后台都为该应用程序分配了一个文件描述符,无论这个文件的本质如何,该文件描述符为...
3. Finding Open Files Filling a File System === Oh! Oh! /tmp is filling and ls doesn't show that any large files are being created. Can lsof help? Maybe. If there's a process that is writing to a file that has been unlinked, lsof may be able to discover the process for ...
