Unable to execute Apache Karaf client output

Question

I started Apache Karaf 3.0.0 in server mode using $KARAF_HOME/bin/startCentOS 6.5. Then I wanted to run several commands using $KARAF_HOME/bin/client, as well as capture the output of these commands to make sure that the commands completed successfully. The output resulted in my console, but I could never redirect it to a file. It seems that Karaf is not writing anything to the output stream or the error stream. I tried the following:

[apache-karaf-3.0.0]$ ./bin/start clean
[apache-karaf-3.0.0]$ ./bin/client "bundle:list"
Logging in as karaf
282 [pool-2-thread-3] WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier - Server at /0.0.0.0:8101 presented unverified key:

[apache-karaf-3.0.0]$ ./bin/client "bundle:list" >& bundleList
[apache-karaf-3.0.0]$ cat bundleList
null

Nothing is written to the file bundleList. It seems that output output does not help.
