Unix-like commands and Windows Command Prompt commands can often accomplish the same task, but a matching purpose does not mean matching syntax, defaults, or behavior. The comparisons below are practical starting points, not universal one-to-one equivalents.
Scope: “DOS” is often used loosely to mean Windows Command Prompt (CMD). The references here chiefly cover CMD and Microsoft’s current Coreutils for Windows package, not every historical version of standalone MS-DOS. Microsoft describes that package as native Unix-style utilities for Windows and separately notes DOS-style ports of find and sort (Microsoft Learn overview).

What does a Unix/DOS command comparison mean?
It is a comparison of commands by the task they perform: listing files, copying a file, moving or renaming something, removing a file, locating a path, or displaying text. It does not establish that commands accept the same options, act on the same kinds of input, or produce the same output.

“Unix-like” is also broader than one implementation. The GNU Coreutils manual documents GNU utilities; its behavior should not automatically be assumed for BSD, macOS, BusyBox, or other systems. On Windows, distinguish built-in CMD commands from utilities supplied by a package. Microsoft’s Coreutils for Windows places Unix-style tools in a Windows environment, where names can coexist with CMD commands and ports (Microsoft Learn overview).
#1 Best Overall
Common commands by task
| Task | Unix-like starting point | Windows CMD starting point | What to check |
|---|---|---|---|
| List directory contents | ls |
dir |
Options, output format, and treatment of hidden entries differ. GNU ls normally omits names beginning with a dot. |
| Copy a file | cp |
copy |
Check whether the input is a file or directory and which options are available. GNU cp does not copy directories by default; recursive options are needed. |
| Move or rename | mv |
move |
Similar common purpose, but do not assume identical option or overwrite behavior. |
| Remove a file | rm |
del or erase |
Confirm the target and the command’s scope before running it; removal can be destructive. |
| Find a path or search text | find |
where to locate paths; find to search text in the relevant CMD context |
Clarify what “find” means. Windows has a CMD command named find, and Microsoft also documents a DOS-style find port alongside Unix-style utilities. |
| Display text | cat |
type |
This is a broad task analogy, not a verified complete syntax equivalence. Microsoft’s package command list also includes a Unix-style cat. |
The GNU side of these comparisons is documented in the GNU Coreutils 9.11 manual. Microsoft documents its package’s commands separately in the Coreutils for Windows commands reference. These references support task-level orientation, not a comprehensive equivalence table for every shell or operating-system version.
Why similar commands may behave differently
Names can collide
A command name alone may not tell you which implementation will run. Microsoft’s Windows package includes Unix-style utilities, while CMD also has commands such as find. Check which shell you are using and which utility it invokes before relying on a name.
Defaults can change the result
Even when the task is the same, defaults matter. For example, GNU ls normally excludes dot-prefixed names from its listing, and GNU cp does not copy directories by default. Do not assume another implementation shares those GNU defaults.

Options and output are implementation-specific
Switches, accepted arguments, formatting, and overwrite behavior may differ. A command that looks familiar can still interpret an option or path differently in another shell. Microsoft says each utility in its package supports --help; use that utility-specific help to inspect its syntax (Microsoft commands reference).
How to compare commands safely
- Name the environment. Identify whether you mean GNU or another Unix-like implementation, Windows CMD, or Microsoft’s Coreutils for Windows package. “DOS” alone is not precise enough for a version-specific answer.
- Define the task and target. Specify whether you are listing, copying, moving, deleting, locating a path, or searching text—and whether the target is a file, directory, or text content.
- Check the implementation’s help. For Microsoft’s package, inspect the individual utility with
--help. For GNU utilities, consult the relevant command entry in the GNU manual. - Verify consequential behavior before execution. Pay particular attention to recursion, hidden entries, overwrite behavior, and removal scope. Do not transfer options from one command merely because its name or purpose looks similar.
What this comparison does not establish
The table is not an exhaustive catalog of Unix, Windows, or historical MS-DOS commands. The Microsoft references describe its Windows package and current documentation, not a version-by-version history of standalone MS-DOS. They also do not establish regional command variants.
A useful command reference should therefore state its shell and implementation, then compare commands by task. Treat each pairing as a place to start, and verify exact syntax and behavior in the environment where the command will run.
