fileutil::magic::filetype(n)					  file utilities				      fileutil::magic::filetype(n)

__________________________________________________________________________________________________________________________________________________

NAME

       fileutil::magic::filetype - Procedures implementing file-type recognition

SYNOPSIS

       package require Tcl  8.4

       package require fileutil::magic::filetype  ?1.0.2?

       ::fileutil::magic::filetype filename

_________________________________________________________________

DESCRIPTION

       This package provides a command for the recognition of file types in pure Tcl.

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

       Beware! This recognizer is large, about 276 Kilobyte of generated Tcl code.

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

	      The output of the command for the specified file is a string describing the type of the file.

	      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.
