# This file contains the dictionary of file format identifiers (magic strings)
# used by file(1).  The fields of this file are as follows:
#
# (1) byte offset
# (2) value type
# (3) optional operator (= by default)
# (4) value to match (numeric or string)
# (5) string to be printed
#
# Numeric values may be decimal, octal, or hex.  Also note that the last string
# may have one printf format specifier.  The '>' in occassional column 1's is
# magic: it forces file(1) to continue scanning and matching additional lines.
# The first line afterwards not so marked terminates the search.
#
# The entries for ELF are not needed anymore, as file(1) now uses the elf(3ELF)
# routines to look at ELF files.  They remain, commented out, for reference.

# Audio files are always big-endian so there are two sets of tables here.
# The CPU endian architecture is determined via the ordering of the first 4 bytes
# (the string ".snd"). The tables below have this value represented as a single
# 4 byte long. If the architecture is big-endian the %d token can be used for
# interpreting the sampling rate.
# Since %d can't be done on the data for little endian machines the limitation
# is that sampling rates not included in the x86 entries will not be recognized.
