About .command Files
.COMMAND files are plain text shell scripts that run a series of terminal commands.
They use the MIME type text/x-sh, which marks them as Unix shell scripts.
- Primary use: Automate repetitive command line tasks on macOS.
- Double-clicking them in the Finder opens the Terminal to execute the commands.
- Edit them with text editors like TextEdit, Sublime Text, or Visual Studio Code.
- Distribute commands in a simple, editable format.
Based on information from FilExt.com, these files simplify system operations on Mac computers.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .command file?
A .command file is a script used on macOS to automate tasks via the Terminal. It contains plain text commands that the operating system executes sequentially, similar to a batch file on Windows. These files identify as the MIME type text/x-sh.
How do I run a .command file on my Mac?
You can run the script by simply double-clicking the file in the macOS Finder. This action automatically launches the Terminal application and executes the commands contained within the file. If it does not run, check the file permissions.
Why do I get a "permission denied" error?
This error occurs because the file lacks the necessary "execute" permission. To fix this, open the Terminal, type chmod +x, press space, drag the file into the Terminal window, and press Enter. This makes the script executable.
How can I edit a .command file?
Since these are plain text files, you can edit them with any text editor like TextEdit, Visual Studio Code, or Sublime Text. Right-click the file and select "Open With" to choose an editor instead of running the script.
Can I open .command files on Windows?
Not natively, as .command files contain Unix-based shell commands specific to macOS or Linux environments. To perform similar actions on Windows, you would typically convert the script into a .bat (Batch) or .ps1 (PowerShell) file.
Are .command files safe?
They can be dangerous if downloaded from untrusted sources because they can execute powerful system-level commands. Always inspect the code in a text editor before running an unfamiliar .command file to ensure it doesn't contain malicious instructions.
What is the difference between .command and .sh files?
Both file types contain shell scripts and share the text/x-sh MIME type. The main difference is that macOS defaults to running .command files in the Terminal when double-clicked, whereas .sh files often open in a text editor unless configured otherwise.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
