![]() ![]() beqdate An eight-byte value in big-endian byte order, interpreted as a Unixĭate. bedate A four-byte value in big-endian byte order, interpreted as a Unixĭate. bedouble A 64-bit double precision IEEE floating point number in big-endianīyte order. befloat A 32-bit single precision IEEE floating point number in big-endianīyte order. bequad An eight-byte value in big-endian byte order. belong A four-byte value in big-endian byte order. beshort A two-byte value in big-endian byte order. qldate An eight-byte value interpreted as a UNIX-style date, but interpretedĪs local time rather than UTC. ldate A four-byte value interpreted as a UNIX-style date, but interpreted as qdate An eight-byte value interpreted as a UNIX date. date A four-byte value interpreted as a UNIX date. pstring A Pascal-style string where the first byte is interpreted as the an Lower and upper case characters in the target, whereas upper caseĬharacters in the magic only match uppercase characters in the Insensitive matching: lowercase characters in the magic match both The “b” flag treats every blank in the target as an Needs at least n consecutive blanks to match. The magic has n consecutive blanks, the target The target, which must contain at least one whitespace character. The string type specification can be optionallyįollowed by /*. double A 64-bit double precision IEEE floating point number in this machine's float A 32-bit single precision IEEE floating point number in this machine's quad An eight-byte value in this machine's native byte order. ![]() long A four-byte value in this machine's native byte order. short A two-byte value in this machine's native byte order. The possible values are:īyte A one-byte value. The line consists of the following fields: offset A number specifying the offset, in bytes, into the file of the data which A testĬompares the data starting at a particular offset in the file with a byte To be tested for, what message to print if a particular magic number isįound, and additional information to extract from the file.Įach line of the file specifies a test to be performed. The file /etc/magic specifies what magic numbers are Test for whether the file contains certain “magic patterns”. file(1) identifies the type of a file using, among other tests, a This manual page documents the format of the magic file as used byĬommand.
