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

-C, --compile
        Write a magic.mgc output file that contains a pre-parsed version of the magic file or directory.

-c, --checking-printout
        Cause a checking printout of the parsed form of the magic file.  This is usually used in
        conjunction with the -m flag to debug a new magic file before installing it.

-e, --exclude testname
        Exclude the test named in testname from the list of tests made to determine the file type.  Valid
        test names are:

-F, --separator separator
        Use the specified string as the separator between the filename and the file result returned.
        Defaults to ‘:’.

-f, --files-from namefile
        Read the names of the files to be examined from namefile (one per line) before the argument list.
        Either namefile or at least one filename argument must be present; to test the standard input, use
        ‘-’ as a filename argument.

-h, --no-dereference
        option causes symlinks not to be followed (on systems that support symbolic links).  This is the
        default if the environment variable POSIXLY_CORRECT is not defined.

-i, --mime
        Causes the file command to output mime type strings rather than the more traditional human readable
        ones.  Thus it may say ‘text/plain; charset=us-ascii’ rather than “ASCII text”.

--mime-type, --mime-encoding
        Like -i, but print only the specified element(s).

-k, --keep-going
        Don't stop at the first match, keep going.  Subsequent matches will be have the string ‘\012- ’
        prepended.  (If you want a newline, see the -r option.)

-l, --list
        Print information about the strength of each magic pattern.

-L, --dereference
        option causes symlinks to be followed, as the like-named option in ls(1) (on systems that support
        symbolic links).  This is the default if the environment variable POSIXLY_CORRECT is defined.

-l      Shows sorted patterns list in the order which is used for the matching.

-m, --magic-file magicfiles
        Specify an alternate list of files and directories containing magic.  This can be a single item, or
        a colon-separated list.  If a compiled magic file is found alongside a file or directory, it will
        be used instead.

-N, --no-pad
        Don't pad filenames so that they align in the output.

-n, --no-buffer
        Force stdout to be flushed after checking each file.  This is only useful if checking a list of
        files.  It is intended to be used by programs that want filetype output from a pipe.

-p, --preserve-date
        On systems that support utime(3) or utimes(2), attempt to preserve the access time of files
        analyzed, to pretend that file never read them.

-r, --raw
        Don't translate unprintable characters to \ooo.  Normally file translates unprintable characters to
        their octal representation.

-s, --special-files
        Normally, file only attempts to read and determine the type of argument files which stat(2) reports
        are ordinary files.  This prevents problems, because reading special files may have peculiar
        consequences.  Specifying the -s option causes file to also read argument files which are block or
        character special files.  This is useful for determining the filesystem types of the data in raw
        disk partitions, which are block special files.  This option also causes file to disregard the file
        size as reported by stat(2) since on some systems it reports a zero size for raw disk partitions.

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

-z, --uncompress
        Try to look inside compressed files.

-0, --print0
        Output a null character ‘\0’ after the end of the filename.  Nice to cut(1) the output.  This does
        not affect the separator which is still printed.

--help  Print a help message and exit.
