PERL (.perl)
.perl file signature | text/x-perl
Perl source files are plain text programs written in the Perl programming language, which was created by Larry Wall and is maintained by the Perl community and The Perl Foundation. They are used for scripting, text processing, system administration, web back ends, and automation tasks, and are commonly executed by the Perl interpreter. As executable source code, Perl files should be reviewed before running, especially when obtained from untrusted sources.

Frequently Asked Questions
What is a .perl file?
A .perl file is identified by the magic bytes 65 76 61 6C 20 22 65 78 65 63 20 2F 75 73 72 2F 6C 6F 63 61 6C 2F 62 69 6E 2F 70 65 72 6C at byte offset 0. Perl source files are plain text programs written in the Perl programming language, which was created by Larry Wall and is maintained by the Perl community and The Perl Foundation. They are used for scripting, text processing, system administration, web back ends, and automation tasks, and are commonly executed by the Perl interpreter.

What are the magic bytes for .perl files?
The magic bytes for PERL files are 65 76 61 6C 20 22 65 78 65 63 20 2F 75 73 72 2F 6C 6F 63 61 6C 2F 62 69 6E 2F 70 65 72 6C at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .perl file?
To validate a .perl file, read the first bytes of the file and compare them against the known magic bytes (65 76 61 6C 20 22 65 78 65 63 20 2F 75 73 72 2F 6C 6F 63 61 6C 2F 62 69 6E 2F 70 65 72 6C) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .perl files?
The primary MIME type for .perl files is text/x-perl.
Is it safe to open .perl files?
PERL (.perl) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
