Unix-like and Windows Command Prompt commands can often accomplish the same task, but a matching purpose does not mean matching syntax, options, defaults, or behavior. The comparisons below are practical starting points, not universal one-to-one translations.
Scope note: “DOS” is often used informally for Windows Command Prompt, but the Microsoft documentation cited here describes Windows CMD and Microsoft’s current Coreutils for Windows package—not every historical release 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’s overview explains that distinction.
What does a Unix/DOS command comparison mean?
It compares commands by the task they can perform: listing files, copying a file, moving an item, removing a file, searching, or displaying text. The comparison is useful for recognizing a familiar task in another environment. It does not establish that a command accepts the same switches, handles the same cases, or uses the same defaults.

The Unix-side details below that cite GNU documentation refer specifically to GNU Coreutils 9.11; they should not be assumed to describe every BSD, macOS, BusyBox, or other implementation. On Windows, distinguish built-in CMD commands from Unix-style utilities supplied by a package. Microsoft’s current package documentation lists Unix-style commands alongside DOS-style ports, so the shell and implementation matter as much as the command name. Microsoft’s commands reference describes the package and its utilities.

Common commands compared by task
Use this table to identify a likely starting point, then check the help for the command in the shell where you will run it. The Windows entries are common CMD starting points; they are task analogies, not a complete authoritative syntax mapping.
| 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 operation targets a file or directory and what options apply. GNU cp does not copy directories by default; recursive options are needed for that case. |
| Move or rename | mv |
move |
Do not assume identical options or overwrite behavior; verify the command’s help in the target environment. |
| Remove a file | rm |
del or erase |
Confirm the target and effect before running a removal command; syntax and behavior depend on the shell and implementation. |
| Locate a path or search text | find |
where to locate paths; find to search text in the CMD context |
First decide whether you mean locating files or searching file contents. The name find is especially collision-prone because Microsoft documents a DOS-style find port as well as Unix-style utilities. |
| Display text | cat |
type |
This is a broad task analogy. Microsoft’s package command listing includes Unix-style cat; check the exact command available in your shell before relying on a particular syntax. |
The GNU-specific behaviors in the table are documented in the GNU Coreutils 9.11 manual. The Microsoft package’s command list is documented separately; neither source turns these task pairs into universal equivalents.
Why similar commands can behave differently
Defaults can change the result
A command can look like the right counterpart and still omit or include different items by default. For example, GNU ls normally leaves out dot-prefixed names, while GNU cp requires recursive options to copy directories. Those are GNU behaviors, not a promise about every Unix-like command or a Windows counterpart.

Pick the symptom - the matching free tool is one click away.
Names can collide across environments
A name such as find does not identify one universal tool. In a Unix-like shell, find is commonly used to locate files by criteria; in CMD, find is associated with searching text. Microsoft’s Windows package also includes Unix-style utilities, so which command runs can depend on what is installed and how the shell resolves it.
Options and pipelines belong to a particular shell
Do not copy a command line solely because its command name appears in a comparison chart. Check the active shell, the actual implementation, the available options, and whether the operation concerns files, directories, or text. A Unix-style utility installed on Windows may accept Unix-style options; a built-in CMD command has its own syntax.
How to check a command before using it
- Identify the shell. Establish whether the command will run in a Unix-like shell, Windows Command Prompt, or a Windows environment with Microsoft’s Coreutils package.
- Identify the implementation. For GNU-specific behavior, consult the GNU Coreutils manual. For Microsoft’s packaged utilities, use its command reference.
- Inspect the command’s help. Microsoft says each utility in its package supports
--help. Use that package-specific help to check accepted options and syntax; do not assume the same help convention applies to every CMD command. - Match the task and target. Confirm whether you are listing, copying, moving, deleting, locating a path, searching text, or displaying text—and whether the target is a file or directory.
- Check consequential behavior before execution. For copying, moving, or deleting, verify the destination, scope, and overwrite or removal effect in the command’s own documentation rather than inferring them from a counterpart’s behavior.
How to read “DOS” command charts
For a quick comparison, read each pair as “a common command for a similar task,” not “the same command under a different name.” If a chart says rm corresponds to del, that is a useful orientation for removing files; it does not prove identical flags or defaults. If precision matters, require the chart to name its shell and implementation, and consult version-appropriate documentation. The sources cited here cover GNU Coreutils 9.11 and Microsoft’s current Windows Coreutils documentation, not a version-by-version history of standalone MS-DOS.
