Net stat network statistics is a command-line tool that displays network connections , both incoming and outgoing, routing tables and a number of network interface statistics. It is available on Unix, Unix-like, and Windows NT-based operating systems.

It is used for finding problems in the man netstat network and to determine the amount of traffic on the network as a performance measurement. Under Linux, raw data is often obtained from the net/dev to work around where some problem in the networking arises until such time as the problem is corrected. On the Windows platform, netstat information can be retrieved by calling the GetTcpTable and GetUdpTable functions in the IP Helper API, or IPHLPAPI.DLL. Information returned includes local and remote IP addresses, local and remote ports, and (for GetTcpTable) TCP status codes. In addition to the command-line netstat.exe tool that ships with Windows, GUI-based netstat programs are available.

In Unix-like and some other operating systems work in an advanced manner which first find a command-line utility that searches through one or more directory trees of a file system, locates files based on some user-specified criteria and applies a user-specified action on each matched file. The possible search criteria include a pattern to match against the file name or a time range to match against the modification time or access time of the file. By default, find returns a list of all files below the current working directory.

The related locate programs use a database of indexed files obtained through find (updated at regular intervals, typically by cron job) to provide a faster method of searching the entire filesystem for files by name. This sacrifices overall efficiency (because filesystems are regularly interrogated even when no users needs information) and absolute accuracy (since the database is not updated in real time) for significant speed improvements (particularly on very large filesystems).

On fast systems with small drives, locate is not necessary or desirable. The three options control how the find command should treat symbolic links. The default behaviour is never to follow symbolic links. This can be explicitly specified using the -P flag. The -L flag will cause the find command to follow symbolic links. The -H flag will only follow symbolic links while processing the command line arguments.

At least one path must precede the expression. Find is capable of interpreting wildcards internally and commands must be constructed carefully in order to control shell globbing. Thus the man netstat system runs networking very precisely and in such a way to make the work easy and time saving. Also it is helpful to solve almost all the problems relating to networking.
