DOS (Disk Operating System) provides a command-line interface for managing files, directories, and system tasks. Below is an overview of some common DOS commands:
1. DIR
Displays a list of files and subdirectories in the current directory.
2. CD
Changes the current directory (e.g., `CD subdirectory` to enter a folder, or `CD ..` to go up one level).
3. MD
Creates a new directory (e.g., `MD newfolder`).
4. RD
Removes an empty directory (e.g., `RD foldername`).
5. COPY
Copies one or more files from one location to another (e.g., `COPY sourcefile destination`).
6. DEL or ERASE
Deletes one or more files (e.g., `DEL filename`).
7. REN or RENAME
Renames a file or directory (e.g., `REN oldname newname`).
8. TYPE
Displays the contents of a text file on the screen (e.g., `TYPE filename.txt`).
9. FORMAT
Formats a disk drive to prepare it for use (e.g., `FORMAT A:`; use with caution as it erases data).
10. CLS
Clears the screen, removing all text from the command prompt window.
11. ECHO
Displays messages or turns command echoing on or off (e.g., `ECHO Hello World`).
12. EXIT
Quits the command prompt and returns to the operating system.
13. HELP
Provides information about DOS commands (e.g., `HELP DIR` for specific command details).
These commands can be used in the DOS command prompt. For more advanced usage, combine commands with options (e.g., `/S` for subdirectories). Always exercise caution with commands that modify files or disks.
