"CMD, cmd or cmd.exe, also known as Command Prompt, is the command-line interpreter in the OS/2, eComStation, Windows NT, Windows CE, and ReactOS operating systems.
It is the counterpart of COMMAND.COM in DOS and Windows 9x systems, and analogous to the Unix shells used on Unix-like systems." - Wikipedia
Chapter 1 started with Ping, TraceRt and NSLookUp. Chapter 2 continued with IPConfig, NetStat and ARP.
Let's start this chapter with a few more commands with PowerCFG / ShutDown / SystemInfo.
PowerCFG is a command-line utility that is used from an elevated Windows Command Prompt to control all configurable power system settings, including hardware-specific configurations that are not configurable through the Control Panel, on a per-user basis.
There are plenty of options to use with PowerCFG. The command I use the most is the /h or Hibernate.
I come across dashboard computers where their only purpose is to display statistics. Some of these machines are limited hardware and small hard drives.
Turning off Hibernate will return to you about 800 MB and sometimes more of available disk space.
If the machine is always on then Hibernate is not required.
ShutDown enables you to shut down or restart local or remote computers one at a time.
There are times when the machine doesn't have a shutdown option or the machine is in an area where you cannot access it physically.
We can use ShutDown to reboot or shutdown a machine. The /m \\<domain name of machine or IP address> will connect us to the machine in our network where we do what is required.
SystemInfo displays detailed configuration information about a computer and its operating system, including operating system configuration, security information, product ID, and hardware properties (such as RAM, disk space, and network cards)
SystemInfo displays Computer name, OS version, OS configuration, OS type, Install Date, System uptime data, BIOS version, Available physical memory, Processor model, Hotfixes installed, Network cards information, Domain name of the computer, System Locale, Time Zone and many other details.
PowerCFG, Shutdown and SystemInfo are great tools to use. Ping, TraceRt, NSLookUp, IPConfig, NetStat, ARP, PowerCFG, ShutDown and SystemInfo are my top 9 Command Prompt applications.
