The mkdir (make directory) command in the Unix, DOS, DR FlexOS, [1] IBM OS/2, [2] Microsoft Windows, and ReactOS [3] operating systems is used to make a new directory. It is also available in the EFI shell [4] and in the PHP scripting language. In DOS, OS/2, Windows and ReactOS, the command is often abbreviated to md.
DOS Shell was one of the first successful attempts to create a basic graphical user interface (GUI) type file manager in DOS, although it is properly referred to as a text user interface (TUI) or Character-Oriented Windows (COW) even though graphical modes were available on supported hardware (VGA-equipped PCs).
A shell script can provide a convenient variation of a system command where special environment settings, command options, or post-processing apply automatically, but in a way that allows the new script to still act as a fully normal Unix command. One example would be to create a version of ls, the command to list files, giving it a shorter ...
MS-DOS Prompt in Windows 95 Command Prompt in Windows 10. All versions of Microsoft Windows have had an MS-DOS or MS-DOS-like command-line interface called MS-DOS Prompt which redirected input to MS-DOS and output from MS-DOS to the MS-DOS Prompt, or, in later versions, Command Prompt.
In MS-DOS, a batch file can be started from the command-line interface by typing its name, followed by any required parameters and pressing the ↵ Enter key. When DOS loads, the file AUTOEXEC.BAT, when present, is automatically executed, so any commands that need to be run to set up the DOS environment may be placed in this file.
The most notable example is the cd command, which changes the working directory of the shell. Since each executable program runs in a separate process , and working directories are specific to each process, loading cd as an external program would not affect the working directory of the shell that loaded it.
Earlier versions of 4OS2 can be run under Windows NT, and OS/2 can run the two DOS and Windows NT shells, all three can be used on Windows NT-type machines and OS/2 multiple boot machines. Among the many commands, statements and functions in 4DOS and lacking in DOS/Windows 95–98 COMMAND.COM are reading keyboard input and a simpler method of ...
This process is referred to as "creating a filesystem" in Unix, Linux, or BSD. [4] Under these systems different commands are used. The commands can create many kinds of file systems, including those used by DOS, Windows, and OS/2.
