WRITE SHORT NOTES ON:

(1)MD:

The MD or MKDIR command is used to create subdirectories in the root directory or other directories.

Syntax

Creates a directory.

MKDIR [drive:]path

MD [drive:]path

If Command Extensions are enabled MKDIR changes as follows:

MKDIR creates any intermediate directories in the path, if needed.

For example, assume \a does not exist then:

mkdir \a\b\c\d

is the same as:

mkdir \a

chdir \a

mkdir b

chdir b

mkdir c

chdir c

mkdir d

(2)CD:

CD (Change Directory) is a command used to switch directories in MS-DOS. For example, if you needed to run Windows 3.11 from DOS, you would type:

cd windows - Changing the directory to Windows;

win - To run the win.com file within the windows directory.

CHDIR [/D] [drive:][path]

CHDIR [..]

CD [/D] [drive:][path]

CD [..]

.. Specifies that you want to change to the parent directory.

Type CD drive: to display the current directory in the specified drive.

Type CD without parameters to display the current drive and directory.

Use the /D switch to change current drive in addition to changing current directory for a drive.

If Command Extensions are enabled CHDIR changes as follows:

The current directory string is converted to use the same case as the on disk names. So CD C:\TEMP would actually set the current directory to C:\Temp if that is the case on disk.

CHDIR command does not treat spaces as delimiters, so it is possible to CD into a subdirectory name that contains a space without surrounding the name with quotes. For example:

cd \winnt\profiles\username\programs\start menu

is the same as:

cd "\winnt\profiles\username\programs\start menu"

(3)PROMPT:

Allows you to change the MS-DOS prompt to display more or less information.

Changes the Windows command prompt.

PROMPT [text]

text Specifies a new command prompt.

The prompt can be made up of normal characters and the below special codes:

$Q	= (equal sign)
$$	$ (dollar sign)
$T	Current time
$D	Current date
$P	Current drive and path
$V	Windows version number
$N	Current drive
$G	> (greater-than sign)
$L	& (less-than sign)
$B	\| (pipe)
$H	Backspace (erases previous character)
$E	Escape code (ASCII code 27)
$_	Carriage return and linefeed

Type PROMPT without parameters to reset the prompt to the default setting.

Examples

prompt $t $d$_$p$g
