The / p switch prints out page information.
6.chkdsk
Chkdsk c: / f - check the file system and restore lost clusters.

9.undelete
Undelete drive name: - restore accidentally erased files.
10.diskcopy
Diskcopy drive name: drive name: - create an exact copy of the diskette.
11.print

12.graphics

14.deltree

15.msd

16.edit

17.qbasic
Qbasic - call the BASIC programming language.
18.doskey

20.msav

21.memmaker

22.subst
To create a virtual disk Z on the path B: \ User \ Betty \ Forms, enter the following command: subst z: b: \ user \ betty \ forms Now, instead of entering the full name, you can access the directory by accessing the disk as shown Below: To create a virtual disk (for example, E) that contains files from the ME directory, you should write to the command line: subst e: c: \ me or subst e: c: \ mark \ refis for files from the REFIS directory. The transition to disk E: is performed as a general rule for any disk. This in some cases makes it easier to start programs when the Path command can not already insert a new directory (the total length of directories in the Path command can not exceed 128 bytes). This command can be inserted into the autoexec.bat file, then the virtual disk will be installed permanently. The subst command is also called the synonym definition command for the directory name and is used to not type the directory name that is often used. When creating and deleting files and directories on the virtual disk E: the same thing will happen synchronously and in the ME directory on the C: drive. To create in this way one more second virtual disk F: it is already impossible. There are no visible changes in the operating or disk memory when creating a virtual disk. The command to remove the virtual disk E: subst e: / d.
23.restart
For DOS mode, there is a command RESTART (reboot), the program which is in C: \ WINDOWS \ COMMAND \ EBD \ EBD.CAB, from which RESTART.COM is extracted and placed in a convenient place. For WINDOWS, you can use programs written in VB, C ++, DELFI and other languages, or you can use the following command file: <command package> RESTART If restart.com is in directory C:
24.tracert
