Let's start with dir

DIR attributes]]
sortorder]] timefield]]


Specifies the drive, directory, and/or files to list.

/A Displays files with specified attributes.
attributes D directory R read-only file
H hidden file A file ready for archiving
S system file - prefix meaning "not"
/B Uses bare format (no header information or summary).
/C Displays thousand separator in file sizes. This is the default. Use /-C to
disable separator display.
/D Same as wide but files are listed in columns.
/L Uses lowercase.
/N New long list format where filenames are on the far right.
/O Lists files in sorted order.
sortorder N by name (alphabetic) S by size (smallest first)
E by extension (alphabetic) D by date/time (oldest first)
G directories first - prefix to reverse order
/P Pauses after each screenful of information.
/Q Displays file owner.
/S Displays files in specified directory and all subdirectories.
/T Controls which time field to display or use for sorting.
timefield C creation time
A last access time
W last written time
/W Uses wide list format.
/X Displays short names generated for non 8dot3 filenames. The format is that of /N with the short name inserted before the long name. If there is no short name, blanks are displayed in its place.
/4 Uses four-digit year

Switches may be pre-set in the DIRCMD environment variable. To override pre-set switches, prefix with - (hyphen). For example, /-W.

cd
Displays the name of the current directory or changes the current directory.

CHDIR
CHDIR
CD
CD

.. Specifies to change to the parent directory.

Typing CD drive: displays the current directory on the specified drive.
Typing CD by itself displays the current drive and directory.

Using the /D command-line switch changes the current drive in addition to changing the current directory of the drive.

If extended command handling is enabled, CHDIR will change as follows:

The current directory string is converted to use the case of the letters on the disk. So, if the case on the disk is like this, CD C:\TEMP will set the current directory to C:\Temp.

The CHDIR command does not treat spaces as delimiters, so it is possible to change the directory name to a subdirectory name with spaces but without quotes. For example:

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

is the same as:

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

In the case where extended functionality is disabled, you must type the above command.

Create directory.

MKDIR path
MD path

If command extensions are enabled, MKDIR will change as follows:

If necessary, MKDIR will create intermediate directories in the path. For example: Suppose \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

Same. If extensions are disabled, you need to type mkdir \a\b\c\d.

Delete a directory.

RMDIR path
RD path

/S In addition to the directory itself, all subdirectories and
files under the specified directory will also be deleted. Used to delete the directory tree.

/Q Quiet mode, when deleting the directory tree with /S, no confirmation is required

Copy one or more files to another location.

COPY source
]

source Specifies the file(s) to copy.
/A Indicates an ASCII text file.
/B Indicates a binary file.
/D Allows decrypting the target file to be created
destination Specifies the directory and/or filename for the new file.
/V Verifies that new files are written correctly.
/N When copying a file with a non-8dot3 name, use the short filename
if possible.
/Y Suppresses prompting to confirm rewriting an existing target file.
/-Y Prompts to confirm rewriting an existing target file.
/Z Copies a networked file in restartable mode.

The command-line switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line. Unless the COPY command
is executed in a batch script, the default is to prompt on overwrite.

To append files, specify a single file for destination and several files for
source (using wildcards or file1+file2+file3 format).

Display or change file attributes.

ATTRIB filename]
]

+ Set attribute.
- Clear attribute.
R Read-only file attribute.
A Archive file attribute.
S System file attribute.
H Hidden file attribute.

Specify the file attributes to be processed.
/S Process matching files in the current folder and its subfolders.
/D Also process folders.

Display the folder structure of a drive or path graphically.

TREE

/F Displays the names of the files in each folder.
/A Uses ASCII characters instead of extended characters.

.ext Specifies the file extension associated with the file type
fileType Specifies the file type associated with the file extension

Type ASSOC without parameters to display current file associations. If you call ASSOC with only a file extension, it displays the current file association for that file extension. If you do not specify any parameters for the file type, the command deletes the association for the file extension.

The AT command is used to schedule commands and programs to run at specific dates and times.

To use the AT command, the Scheduling Service must be running.

"command" The Windows NT command or batch program to be run.

break

If command extensions are enabled and the operating platform is Windows XP, the BREAK command will enter a hard-coded breakpoint when being debugged by a debugging program.
