In computing, fc
(File Compare) is a command-line program in DOS, IBM OS/2 and Microsoft Windows operating systems, that compares multiple files and outputs the differences between them. [2] [3] It is similar to the Unix commands comm
, cmp
and diff
.
The fc
command has been included in Microsoft operating systems since MS-DOS 2.11 (e.g. on the 1984/85 DEC Rainbow release) [4] and is included in all versions of Microsoft Windows. [5] fc
has also been included in IBM OS/2 Version 2.0. [6]
DR DOS 6.0 includes an implementation of the fc
command. [7]
The command is also available in FreeDOS. This implementation is licensed under the GPLv2+. [8]
fc
can compare text files as well as binary files. [9] The latest versions[ which? ] can compare ASCII or Unicode text. The result of comparisons are output to the standard output. The output of fc
is intended primarily to be human readable and may be difficult to use in other programs.
Edlin is a line editor, and the only text editor provided with early versions of IBM PC DOS, MS-DOS and OS/2. Although superseded in MS-DOS 5.0 and later by the full-screen MS-DOS Editor, and by Notepad in Microsoft Windows, it continues to be included in the 32-bit versions of current Microsoft 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.
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
.
In computing, CLS
is a command used by the command-line interpreters COMMAND.COM
and cmd.exe
on DOS, Digital Research FlexOS, IBM OS/2, Microsoft Windows and ReactOS operating systems to clear the screen or console window of commands and any output generated by them. It does not clear the user's history of commands, however. The command is also available in the DEC RT-11 operating system, in the open-source MS-DOS emulator DOSBox and in the EFI shell. In other environments, such as Linux and Unix, the same functionality is provided by the clear
command.
DOSKEY is a command for DOS, IBM OS/2, Microsoft Windows, and ReactOS that adds command history, macro functionality, and improved editing features to the command-line interpreters COMMAND.COM
and cmd.exe
.
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, 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, 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, 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, find
is a command in the command-line interpreters (shells) of a number of operating systems. It is used to search for a specific text string in a file or files. The command sends the specified lines to the standard output device.
In computing, label
is a command included with some operating systems. It is used to create, change, or delete a volume label on a logical drive, such as a hard disk partition or a floppy disk. Used without parameters, label
changes the current volume label or deletes the existing label.
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, copy
is a command in various operating systems. The command copies computer files from one directory to another.
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.
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, comp
is a command used on DEC OS/8, DOS, DR FlexOS, IBM OS/2, Microsoft Windows and related computer operating systems such as ReactOS. It is used to perform comparisons of multiple computer files to show the differences between them.
In computing, diskcomp
is a command used for comparing the complete contents of a floppy disk to another one.
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.
The command-line tool exe2bin
is a post-compilation utility program available on MS-DOS and other operating systems.
