[Tinyos-devel] backslash problem in tos-locate-jre

[Razvan Musaloiu-E.]

Hi!

I just notice a small problem in the tos-locate-jre script from 
tinyos-2.x/tools/tinyos/misc/tos-locate-jre. Line 41 is this:
     jhome=`regtool -q get '\HKLM\SOFTWARE\JavaSoft\Java Development Kit\'$jversion'\JavaHome'`
On a bash 3.0 in Linux and a bash 3.2 in Cygwin everything is fine but on 
a bash 3.1 on Linux the \' generates a parsing error because backslash is 
interpreted as an escape character. The attached script fixes the problem 
but escaping all the backslashes.

How the error looks like:
  	$ ./tos-locate-jre --javac
  	./tos-locate-jre: line 134: unexpected EOF while looking for matching ``'
  	./tos-locate-jre: line 147: syntax error: unexpected end of file
  	$ bash --version
  	GNU bash, version 3.1.17(1)-release (i686-redhat-linux-gnu)
  	Copyright (C) 2005 Free Software Foundation, Inc.

How to apply the patch:
  	$ cd $TOSROOT
  	$ patch -p0 < tos-locate-jre.patch
