strange behavior of shellscript component

Hello,

I want to execute the shell command "echo `hostname -f` > /tmp/foo.txt" 
with the new shellscript component. Executing this command with 
os.runshell works, but with the schellscript components I'm running into 
trouble. The below descripton does not work, in fact I get a file 
"/tmp/foo.txt],".  with the content

MARK - done HOST oplabox03.cern.ch:rootProcess:test:shell [[echo 
oplabox03.cern.ch 2005/07/05 16:40:12:163 CEST] Exit code#: 0

BTW, I have to define my own bash shell as the BashExec component defined 
in org/smartfrog/services/shellscript/components.sf has "/etc/bash" as 
cmd. This is not available on my machine; I think it would be better to 
define cmd as "/bin/bash" which should be available on standard Linux 
machines. Here's the component description. Do you know why it does not work ?

#include "org/smartfrog/services/shellscript/components.sf"

localShellExec extends ShellExec {
 cmd ["/bin/bash"];
 echoErrorCmd "$?";
}

localShell extends Shell {
  exec extends localShellExec;
}

sfConfig extends Compound {
 shell extends localShell;
 doScript extends Script {
  shell LAZY ATTRIB shell;
  startScript ["echo `hostname -f` > /tmp/foo.txt"];
  autoTerminate true;
 }
}



Thank you very much for your help.
Best regards,
Andreas
