DIR (2)

DOS Version 5.00:

DOS 5.00 introduced a number of new DIR parameters which are summarized in the following list. In addition to the new parameters, DOS 5.00 also displays the number of bytes contained in the files in the listed directory. Prior DOS versions only displayed the number of files in the listed directory.

DIR/A:attribute- Displays files having certain file attributes, where attribute is one of the following:

h     hidden files
-h    nonhidden files
s      system files
-s     nonsystem files
d     directory names
-d    files only (no directory names)
a     files that need archiving (backup)
-a    files that have been archived
r     read-only files
-r    files that are not read-only

DIR /A:r-h- Displays read-only files that are not hidden.

DIR /B-Displays a bare filename listing without size, date, and time information.

DIR /L-Displays file information in lowercase.

DIR /O: sort order - Specifies sort order by name, extension, date, or
file size, where sort order is:

 n                 alphabetical by name (default value if no sort order
                    is specified).

-n                descending alphabetical order by name
                   alphabetical by extension.

 e                alphabetical by extension.

-e                descending alphabetical order by extension.
               
 d                date and time order (earliest first).

-d               date and time order (most recent first)

 s               file size (smallest first).

-s               file size (largest first).

 g              directories grouped before files (default).

-g              directories grouped after files.

DIR: /0 :-d/p-Sorts the directory with the most recently saved tless

listed first. The ip pauses the directory display.

DIR /0:e-s-Displays files by extension and then by file size.
DIR S-Displays all files in all sub directories.

The SET DIRCMD Command: if you are using DOS 5.00, you can
place the following lire in your AUTOEXEC.BAT file or enter it
directly from the DOS prompt to preset DIR command parameters. For
example, the command fine SET DIRCMD lo:-gn/p results in paused
directories that are sorted by filename with directory names grouped
at the end of the listing.

Pausing and Restarting a Directory Display: In addition to the /P parameter with DIR command, there are two other ways to pause the directory display. First you can press Ctrl-S or the Pause key, which stops the directory display in its tracks. Press any key to resume the display. If you are using DOS version 2.00 or later, you can pause the dsiplay with MORE filter. This is done by typing DIR|MORE. Pausing the display is often necessary when the directory listing exceeds the number otlines on your screen.

Making, Changing, and Removing Directories

You used the DIR (directory) command in Section 3 to display a list of filenames on the screen. You can create and name multiple disk directories on a disk to allow for the subdivision of your files. This feature lets you group common files into separate directories. This is similar to subdividing information into file cabinet drawers and file folders. This is particularly convenient when you use a fixed disk containing hundreds or even thousands of files. Instead of listing all files in one directory, you can list files in smaller, more manageable sub directories. Lock at the following directory commands.

Path

The PATH command is used to provide access to files located in other directories or on other disks. The PATH command is usually entered as a line in an AUTOEXEC.BAT (or batch) file, which most often contains one or more DOS commands. The AUTOEXEC.BAT file is automatically executed upon system turn-on to run one or more desired programs without the need for user intervention. Other batch  files are executed upon command. When an AUTOEXEC.CAT file is used, each command contained in the file executes as it is encountered. The creation and use of batch files is described in Section 8. To illustrate the PATH command, assume you have a program named GATOR.COM that is located in a sub directory. You are not sure if it is cn disk C or disk A, so you want to search both disks and execute the command when found. To complicate matters, you are not sure if the program is in the SWAMP sub directory or the MUD sub directory. Here is where the PATH command comes to your rescue. To set up a search...
