Unix file recognition is steered by a file called "/etc/magic". It contains rules for what has to be in a file to make it a file of type x. It works like "if a file has an 'x' as the 12th byte and a 'y' as one of the first 3 bytes than it is ...". As this is ultimately best-guess its outcome can be wrong sometimes. This may be the case with your file for reasons unknown.

Issue "file /path/to/your/logfile" to find out which type the system thinks it is (the "file" utility bases its outcome on the same mechanism). You can even correct the type database in "/etc/magic" by putting in new entries - see "man /etc/magic" for details how to do so.

It is also possible that your file contains some unprintable characters "less" filters out, which make "file" think it is binary. In this case you probably should correct your logging mechanism because writing hex characters in a log file is wrong.

I hope this helps.

__________________________________________________________________________________________________________________________________________________

NAME

       fileutil::magic::mimetype - Procedures implementing mime-type recognition

SYNOPSIS

       package require Tcl  8.4

       package require fileutil::magic::mimetype  ?1.0.2?

       ::fileutil::magic::mimetype filename

_________________________________________________________________

DESCRIPTION

       This package provides a command for the recognition of file types in pure Tcl. The output is standardized to mime-types.

       The  core  part	of the recognizer was generated from a "magic(5)" file containing the checks to perform to recognize files, and associated
       mime-types.

       ::fileutil::magic::mimetype filename
	      This command is similar to the command fileutil::fileType.

	      The output of the command for the specified file is not a list of attributes describing the type of the file, but a list of standard
	      mime-types the file may have.

	      This list will be empty if the type of the file is not recognized.

REFERENCES

       [1]    File(1)  sources	[ftp://ftp.astron.com/pub/file/]  This site contains the current sources for the file command, including the magic
	      definitions used by it. The latter were used by us to generate this recognizer.

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category fileutil
       :: magic of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may
       have for either package and/or documentation.
