I would be more inclined to use "wc -l < ecoli_eperons", or "grep -c . ecoli_operons", but as I test the code given, it works fine as ilong as the file is readable.

uri_urn(n)					    Tcl Uniform Resource Identifier Management						uri_urn(n)

__________________________________________________________________________________________________________________________________________________

NAME

       uri_urn - URI utilities, URN scheme

SYNOPSIS

       package require Tcl  8.2

       package require uri::urn  ?1.1.2?

       uri::urn::quote url

       uri::urn::unquote url

_________________________________________________________________

DESCRIPTION

       This  package  provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with
       the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri	to
       handle urls using the urn scheme.

COMMANDS

       uri::urn::quote url
	      This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its
	      result.

       uri::urn::unquote url
	      This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from  all  disallowed  characters,
	      and returns the modified urls as its result.

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