>Release:        All FreeBSD RELEASE i386
>Environment:

	All FreeBSD RELEASEs

>Description:

	In a script, if the variable for a file name had a white space at
	the end, the sh will treat it differently when the file name variable
	is used at redirected I/O, from used at fopen(). The white space is
	interpreted as part of the file name when I/O redirections, such as,
	'<', '<<', '>>', and '>' are used. This is a problem for using in
	a script.
	The FreeBSD awk generates such withe space:

		MyArch=`uname -v | awk -F/ '{printf $NF}`
		echo	"=$MyArch="
		=GENERIC =

	I am not sure which one is the problem, maybe both.

>How-To-Repeat:

	For awk problem, see Description above.
	Below is the sh issue:

	% more abc
	file abc is a testing file

	% more test.script
	FILE_NAME="abc "
	more < $FILE_NAME
	echo	"=$FILE_NAME="
	more $FILE_NAME

	% test.script
test.script: cannot open abc : no such file
=abc =
file abc is a testing file


>Fix:
	
	one of them has to be fixed, but I do know which (-:
	Maybe both?
