Description: Perl module to determine file types
File::MimeInfo can be used to determine the mime type of a file. It tries to implement the freedesktop specification for
a shared MIME database.

This package also contains two related utilities:

If a file does not contain the <html> tag, /usr/bin/mimetype identifies the file as text/plain. /usr/bin/file seems to be more intelligent, or more tolerant, in this regard.

Can you please provide an example of a case that mimetype does NOT handle, but /usr/bin/file does handle correctly?

Hi Michiel

Please see attached test file.

My tests:

/usr/bin/mimetype /tmp/mimetestfile

/tmp/mimetestfile: text/plain

file /tmp/mimetestfile

/tmp/mimetestfile: HTML document, ISO-8859 text, with very long lines

Regards,

Jie

Determining that a file is an HTML file when it is called something and not something.html and it merely contains some tags that look like HTML but not the required <html> - I'm not sure if I'd find it correct, it might lead to other sorts of problems. File::MimeInfo does not need to be bug-compatible with /usr/bin/file. Closing.
