       mimetype - Determine file type


       mimetype [options] [-] files


       This script tries to determine the mime type of a file using the Shared MIME-info
       database. It is intended as a kind of file(1) work-alike, but uses mimetypes instead of

       If one symlinks the file command to mimetype it will behave a little more compatible, see
       "--file-compat".  Commandline options to specify alternative magic files are not
       implemented the same because of the conflicting data formats.  Also the wording of the
       descriptions will differ.

       For naming switches I followed the manpage of file(1) version 4.02 when possible. They
       seem to differ completely from the spec in the 'utilities' chapter of IEEE Std 1003.1-2001


       -a, --all
           Show output of all rules that match the file.

           TODO: this method now just returns one match for each method (globs, magic, etc.).

       -b, --brief
           Do not prepend filenames to output lines (brief mode).

           Force the program to look in these directories for the shared mime-info database. The
           directories specified by the basedir specification are ignored.

       -d, --describe
           Print file descriptions instead of mime types, this is the default when using

       -D, --debug
           Print debug information about how the mimetype was determined.

       -f namefile, --namefile=namefile
           Read the names of the files to be examined from the file 'namefile' (one per line)
           before the argument list.

           Make mimetype behave a little more file(1) compatible. This is turned on automatically
           when you call mimetype by a link called 'file'.

           A single '-' won't be considered a separator between options and filenames anymore,
           but becomes identical to "--stdin".  ( You can still use '--' as separator, but that
           is not backward compatible with the original file command. ) Also the default becomes
           to print descriptions instead of mimetypes.

       -F string, --separator=string
           Use string as custom separator between the file name and its mimetype or description,
           defaults to ':' .

       -h, --help
       -u, --usage
           Print a help message and exits.

       -i, --mimetype
           Use mime types, opposite to "--describe", this is the default when _not_ using

       -L, --dereference
           Follow symbolic links.

       -l code, --language=code
           The language attribute specifies a two letter language code, this makes descriptions
           being outputted in the specified language.

       -M, --magic-only
           Do not check for extensions, globs or inode type, only look at the content of the
           file. This is particularly useful if for some reason you don't trust the name or the
           extension a file has.

       -N, --noalign
           Do not align output fields.

           If you want an alternative output format, you can specify a format string containing
           the following escapes:

                   %f for the filename
                   %d description
                   %m mime type

           Alignment is not available when using this, you need to post-process the output to do

           Determine type of content from STDIN, less powerful then normal file checking because
           it only uses magic typing. This will happen also if the STDIN filehandle is a pipe.

           To use this option IO::Scalar needs to be installed.

       -v, --version
           Print the version of the program and exit.


           These variables can list base directories to search for data files. The shared mime-
           info will be expected in the "mime" sub directory of one of these directories. If
           these are not set, there will be searched for the following directories:


           See also the "XDG Base Directory Specification"


       The base dir for all data files is determined by two environment variables, see

           All other files are compiled from these source files. To re-compile them use

           Compiled information about globs.

           Compiled information about magic numbers.

           Descriptions of a mimetype in multiple languages, used for the "--describe" switch.


       If a file has an empty mimetype or an empty description, most probably the file doesn't
       exist and the given name doesn't match any globs. An empty description can also mean that
       there is no description available in the language you specified.

       The program exits with a non-zero exit value if either the commandline arguments failed, a
       module it depends on wasn't found or the shared mime-info database wasn't accessible. See
       File::MimeInfo for more details.


       The '--all' switch doesn't really show all matches, but only one per mime-typing method.
       This needs to be implemented in the modules first.


       If you find bugs, please file them in our Github issue tracker at

       mimetype doesn't provide a switch for looking inside compressed files because it seems to
       me that this can only be done by un-compressing the file, something that defeats the
       purpose. On the other hand the option should exist for strict compatibility with file(1).
       Possibly a subclass should be made for this one day.
