Overview

The command is primarily used to manage network resources. [2] It is an external command implemented as net.exe. [3] When used in a batch file, the /Y or /N switches can be used to unconditionally answer Yes or No to questions returned by the command. [2] The net command has several sub-commands that can differ from one implementation or operating system version to another.

On Windows CE .NET 4.2, [4] Windows CE 5.0 [5] and Windows Embedded CE 6.0, [6] it is available as an external command stored in \Windows\net.exe. This version only supports the use and view sub-commands.

Example

The net use command has several network-related functions.

Connecting network drive and printer

net use can control mounting ("mapping" in Microsoft terminology) drive shares and connecting shared printers in a network environment. This command makes use of the SMB (server message block) and the NetBIOS protocol on port 139 or 445. The basic Windows XP configuration enables this functionality by default. Thus users can connect to and disconnect from shared resources such as computers, printers and drives.

net use can display a list of network-connection information on shared resources.

Null session connections

net use also connects to the IPC$ (interprocess communication share). This is the so-called null session connection, which allows unauthenticated users. The basic syntax for connecting anonymously is:

net use \\IP address\IPC$ "" /u:""

For example, typing at the command prompt:

net use \\192.168.1.101\IPC$ "" /u:""

attempts to connect to the share IPC$ of the network 192.168.1.101 as an anonymous user with blank password. If successfully connected to the target machine, a lot of information can be gathered such as shares, users, groups, registry keys and more. This would provide a hacker with a lot of information about a remote user. This has changed in Windows NT 4.0 SP6 already. In Windows 2000 "null session connections" could have been enabled after changes of the system-configuration.

The cd command, also known as chdir, is a command-line shell command used to change the current working directory in various operating systems. It can be used in shell scripts and batch files.

dir (command) Directory information command on various operating systems

In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. It is one of the basic commands to help navigate the file system. The command is usually implemented as an internal command in the command-line interpreter (shell). On some systems, a more graphical representation of the directory structure can be displayed using the tree command.

mkdir Directory creation command on various operating systems

The mkdir command in the Unix, DOS, DR FlexOS, IBM OS/2, Microsoft Windows, and ReactOS operating systems is used to make a new directory. It is also available in the EFI shell and in the PHP scripting language. In DOS, OS/2, Windows and ReactOS, the command is often abbreviated to md.

<span class="mw-page-title-main">XCOPY</span> Computing command

In computing, XCOPY is a command used on IBM PC DOS, MS-DOS, IBM OS/2, Microsoft Windows, FreeDOS, ReactOS, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network.

more (command) Terminal pager available on various operating systems

In computing, more is a command to view the contents of a text file one screen at a time. It is available on Unix and Unix-like systems, DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows and ReactOS. Programs of this sort are called pagers. more is a very basic pager, originally allowing only forward navigation through a file, though newer implementations do allow for limited backward movement.

In computing, SUBST is a command on the DOS, IBM OS/2, Microsoft Windows and ReactOS operating systems used for substituting paths on physical and logical drives as virtual drives.

<span class="mw-page-title-main">ATTRIB</span>

In computing, ATTRIB is a command in Intel ISIS-II, DOS, IBM OS/2, Microsoft Windows and ReactOS that allows the user to change various characteristics, or "attributes" of a computer file or directory. The command is also available in the EFI shell.

move (command)

In computing, move is a command in various command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS/4NT, and PowerShell. It is used to move one or more files or directories from one place to another. The original file is deleted, and the new file may have the same or a different name. The command is analogous to the Unix mv command and to the OpenVOS move_file and move_dircommands.

ren (command)

In computing, ren is a command in various command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS, 4NT and Windows PowerShell. It is used to rename computer files and in some implementations also directories. It is analogous to the Unix mv command. However, unlike mv, ren cannot be used to move files, as a new directory for the destination file may not be used. Alternatively, move may be used if available. On versions of MS-DOS that do not support the move command, the user would simply copy the file to a new destination, and then delete the original file. A notable exception to this rule is DOSBox, in which ren may be used to move a file, since move is not supported.

<span class="mw-page-title-main">TYPE (DOS command)</span>

In computing, type is a command in various command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS/4NT and Windows PowerShell used to display the contents of specified files on the computer terminal. The analogous Unix command is cat.

del (command) Command in various operating systems

In computing, del is a command in command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS, NDOS, 4OS2, 4NT and Windows PowerShell. It is used to delete one or more files or directories from a file system.

ver (command) Command in many command-line interpreters

In computing, ver is a command in various command-line interpreters (shells) such as COMMAND.COM, cmd.exe and 4DOS/4NT. It prints the name and version of the operating system, the command shell, or in some implementations the version of other commands. It is roughly equivalent to the Unix command uname.

In some operating systems, vol is a command within the command-line interpreters (shells) such as COMMAND.COM and cmd.exe. It is used to display the volume label and volume serial number of a logical drive, such as a hard disk partition or a floppy disk, if they exist.

help (command) Command in various command line shells

In computing, help is a command in various command line shells such as COMMAND.COM, cmd.exe, Bash, qshell, 4DOS/4NT, Windows PowerShell, Singularity shell, Python, MATLAB and GNU Octave. It provides online information about available commands and the shell environment.

copy (command)

In computing, copy is a command in various operating systems. The command copies computer files from one directory to another.

<span class="mw-page-title-main">TIME (command)</span>

In computing, TIME is a command in DEC RT-11, DOS, IBM OS/2, Microsoft Windows and a number of other operating systems that is used to display and set the current system time. It is included in command-line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS, 4OS2 and 4NT.

<span class="mw-page-title-main">Shutdown (computing)</span> Remove power from a computers main components in a controlled way

To shut down or power off a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.

title (command) Command of command line interpreters

In computing, title is a command in various command-line interpreters (shells) on Microsoft Windows and ReactOS that changes the title for the graphical terminal emulator window. The command is also used within DFS and ADFS to change the title of the disc in the current drive.

In computing, findstr is a command in the command-line interpreters (shells) of Microsoft Windows and ReactOS. It is used to search for a specific text string in computer files.

replace (command)

In computing, replace is a command that is used to replace one or more existing computer files or add new files to a target directory. Files with a hidden or system attribute set cannot be replaced using replace. The command lists all files that are replaced.
