The - (minus sign) invokes subcommands which are specified on the command line and should precede nslookup commands. In non-interactive mode, i.e. when the first argument is a name or Internet address of the host being searched, parameters and the query are specified as command line arguments in the invocation of the program.
The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
Some commands are built into the command interpreter; others exist as external commands on disk. Over multiple generations, commands were added for additional functions. In Microsoft Windows , a command prompt window that uses many of the same commands, cmd.exe , can still be used.
ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9]
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
A WHOIS command line client passes a phrase given as an argument directly to the WHOIS server. Various free open source examples can still be found on sites such as sourceforge.net. However, most modern WHOIS tools implement command line flags or options, such as the -h option to access a specific server host, but default servers are preconfigured.
The command removes and corrects preloaded entries using a number of case-sensitive switches. The nbtstat -a < name > command performs a NetBIOS adapter status command on the computer name specified by < name >. The adapter status command returns the local NetBIOS name table for that computer as well as the MAC address of the
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
