In computing, share
is a command for DOS that allows software to perform file locks. Locking files became necessary when MS-DOS began allowing files to be accessed simultaneously by multiple programs, either through multitasking or networking. [1] [2] [3]
On MS-DOS, the command is available in versions 3 and later. [4] The command is also available in FreeDOS, [5] PTS-DOS, [6] and SISNE plus. [7] The FreeDOS version was developed by Ron Cemer and is licensed under the GPL. [8] DR DOS 6.0 [9] and Datalight ROM-DOS [10] include an implementation of the share
command.
Windows XP and later versions include 16-bit commands (nonnative) for the MS-DOS subsystem that are included to maintain MS-DOS compatibility. The share
MS-DOS subsystem command performs functions that are now inherent to Microsoft Windows. It is available to preserve compatibility with existing files, but has no effect at the command line because the functionality is automatic. The 16-bit MS-DOS subsystem commands are not available on 64-bit editions of Windows. [11]
There were five locking modes:
The program runs as a terminate-and-stay-resident program and is typically loaded at boot-up.
share [/F:space] [/L:locks]
/F:space
Allocates file space (in bytes) for file-sharing information./L:locks
Sets the number of files that can be locked at one time.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.
fdisk is a command-line utility for disk partitioning. It has been part of DOS, DR FlexOS, IBM OS/2, and early versions of Microsoft Windows, as well as certain ports of FreeBSD, NetBSD, OpenBSD, DragonFly BSD and macOS for compatibility reasons. Windows 2000 and its successors have replaced fdisk
with a more advanced tool called diskpart
.
Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions. The first version in the 9x series was Windows 95, which was succeeded by Windows 98 and then Windows Me, which was the third and last version of Windows on the 9x line, until the series was superseded by Windows XP.
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.
In computing, Windows on Windows, was a compatibility layer of 32-bit versions of the Windows NT family of operating systems since 1993 with the release of Windows NT 3.1, which extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier. There is a similar subsystem, known as WoW64, on 64-bit Windows versions that runs 32-bit programs.
In computing, exit
is a command used in many operating system command-line shells and scripting languages.
In computing, FASTOPEN
is a DOS terminate-and-stay-resident command, introduced in MS-DOS version 3.3, that provides accelerated access to frequently-used files and directories. The command is also available in SISNE plus.
In computing, tree
is a recursive directory listing command or program that produces a depth-indented listing of files. Originating in PC- and MS-DOS, it is found in Digital Research FlexOS, IBM/Toshiba 4690 OS, PTS-DOS, FreeDOS, IBM OS/2, Microsoft Windows, and ReactOS. A version for Unix and Unix-like systems is also available.
In computing, DELTREE
is a command line command in some Microsoft operating systems, SpartaDOS X and FreeDOS that recursively deletes an entire subdirectory of files.
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.
In computing, the print
command provides single-user print spooling capability in a number of operating systems. It is roughly similar to that provided by the UNIX System V lp and BSD lpr print spooler systems.
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.
In computing, format
, a command-line utility that carries out disk formatting. It is a component of various operating systems, including 86-DOS, MS-DOS, IBM PC DOS and OS/2, Microsoft Windows and ReactOS.
In computing, choice
is a command that allows for batch files to prompt the user to select one item from a set of single-character choices. It is available in a number of operating system command-line shells.
MS-DOS is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS". MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system.
Datalight was a privately held software company specializing in power failsafe and high performance software for preserving data integrity in embedded systems. The company was founded in 1983 by Roy Sherrill, and is headquartered in Bothell, Washington. As of 2019 the company is a subsidiary of Tuxera under the name of Tuxera US Inc.
In computing, diskcopy is a command used on a number of operating systems for copying the complete contents of a diskette to another diskette.
In computing, recover
is a primitive file system error recovery utility included in MS-DOS / IBM PC DOS versions prior to DOS 6.0 and a number of other operating systems.
In computing, diskcomp
is a command used for comparing the complete contents of a floppy disk to another one.
The command-line tool exe2bin
is a post-compilation utility program available on MS-DOS and other operating systems.
