chown remotely via ssh / invalid group

Hi,

i have a problem with a shell script. I need to change the owner and group of a file on a remote machine.

I tried to use ssh but have some problems.

The code:
Code:
group=`ssh -t -t $1 -p 3344 "stat -c %G $cpath/FILE"`

echo " $2:$group "
echo $1
echo $cpath

ssh $1 -p 3344 "chown $2:$group $cpath/FILE

The Output if started with ./script.sh 192.168.0.99 scott
Code:
 scott:users
192.168.0.99
/backup/scott/data

chown: âscott:users\râ: ungültige Gruppe

Note: "ungültige Gruppe" = invalid group (there is a problem with special character " ü ")

Output if startet with sh -x script.sh 192.168.0.99 scott
Code:
++ ssh -t -t 192.168.0.99 -p 3344 'stat -c %G /backup/scott/data/FILE'
Connection to 192.168.0.99 closed.
+ group=$'users\r'

 'echo ' scott:users
 scott:users
+ echo 192.168.0.99
192.168.0.99
+ echo /backup/scott/data
/backup/scott/data

++ ssh 192.168.0.99 -p 3344 'chown scott /backup/scott/data/FILE'
 /backup/scott/data/FILE'wn scott:users
chown: âscott:users\râ: ungültige Gruppe

If i do " chown scott:users /backup/scott/data/FILE " there is no problem.

I think the problem is in the variable $group cuz it is containing this " \r " any hint where this comes from or how to get rid of it ?

Thank you
Greetings Linién

NAME
nih-dbus-tool - D-Bus binding code generator SYNOPSIS
nih-dbus-tool [OPTIONS]... [-o FILE] [XMLFILE] nih-dbus-tool [OPTIONS]... -o FILE --system|--session --dest=NAME OBJECT-PATH DESCRIPTION
OVERVIEW
The D-Bus introspection format is an XML document describing the interfaces implemented by a particular object, including the methods and signals of that interface along with their arguments and the properties of that interface. A single document describes a single object, represented by the root <node> tag. Interfaces implemented by that object are specified by <interface> tags within it. Methods, signals and properties defined by the interface are described by <method>, <signal> and <property> tags within the interface. Arguments to methods and signals are defined by <arg> tags within them. Names and other values are specified as attributes to the tag. Additional properties for external tools or software may be given in <annotation> tags. These may appear within interfaces, methods, sig- nals, properties and arguments. nih-dbus-tool makes use of many of these. Note that argument annotations are an nih-dbus-tool extension to the format. nih-dbus-tool's parser is reasonably liberal, to allow for future expansion of the D-Bus introspection format. Any unknown tag, attribute or annotation, or any tag not in an expected location, will be ignored with a warning. However a missing root node tag, missing attributes, illegal or invalid format values for defined attributes or non well-formed XML will result in an error. Character data and comments are not considered part of description, and are not parsed. OPTIONS
