Table of Contents
The file(1) utility is a UNIX utility that
examines and classifies files, based on information found in its
database of file types, the /etc/magic file. The following
information may be added to your system's /etc/magic file to enable
file(1) to correctly identify Berkeley DB
database files.
The file(1) utility magic(5)
information for the standard System V UNIX implementation of the
file(1) utility is included in the Berkeley DB
distribution for both big-endian (for example, Sparc)
and little-endian (for example, x86) architectures.
See Big-endian magic information
and Little-endian magic information
respectively for this information.
The file(1) utility magic(5)
information for Release 3.X of Ian Darwin's implementation of the
file utility (as distributed by FreeBSD and most Linux
distributions) is included in the Berkeley DB distribution. This
magic.txt information is correct for
both big-endian and little-endian architectures. See the next
section for this information.
