What is MIME type "text/x-perl"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
The MIME type text/x-perl designates files containing Perl code. It tells applications that the file is a text file meant to be processed as a Perl script. The "x-" prefix indicates it is a non-standard or experimental registration.
- It is used for server-side programming, especially in CGI scripts.
- It supports module files and libraries in Perl applications.
- It is also applied to in-line documentation written in Pod.
- It covers both traditional Perl and modern variants like Raku.
This classification helps operating systems, web servers, and editors to treat files appropriately. Files marked with text/x-perl often include those with extensions such as PL, POD, CGI, PM, PLX, PERL, AL, PM6, T, PH, FCGI, 6PL, 6PM, NQP, P6, P6L, P6M, PL6, PSGI, RAKU, and RAKUMOD.
This MIME type enables systems to apply the correct syntax highlighting, execution permissions, and processing rules to the file. It is key for web servers handling dynamic content and for developers working in environments where clear distinction between code and plain text is essential.
Further details are available on the Perl Wikipedia page and the File Extension Database.

Usage Examples
HTTP Header
When serving content with this MIME type, set the Content-Type header:
Content-Type: text/x-perl
HTML
In HTML, you can specify the MIME type in various elements:
<a href="file.dat" type="text/x-perl">Download file</a>
Server-side (Node.js)
Setting the Content-Type header in Node.js:
const http = require('http');
http.createServer((req, res) => {
res.setHeader('Content-Type', 'text/x-perl');
res.end('Content here');
}).listen(3000);

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 are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
