> --------------------------------
>                 Key: KARAF-1226
>                 URL: https://issues.apache.org/jira/browse/KARAF-1226
>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-shell
>    Affects Versions: 2.2.5
>         Environment: Ubuntu 11.10 64-bit, OpenJDK 6
>            Reporter: Hendy Irawan
>         Attachments: KARAF-1226-shell.patch
> Example usage:
> {code}
> echo osgi:ls | bin/client
> {code}
> or:
> {code}
> bin/client < commands.karafsh
> {code}
> or redirecting stdout to file:
> {code}
> echo osgi:ls | bin/client > bundles.txt
> {code}
> Expected outcome:
> 1. Output of the command printed to stdout
> 2. Banners etc. (if any) printed to stderr
> 3. Shell prompt should not be output at all
> 4. The client exits immediately
> Actual behavior:
> 1. All output including banners and the shell prompt are printed to stdout (only)
> 2. The client then hangs but still using around 20% CPU usage. It's not possible to Ctrl+C,
and need to kill the process.
> GNU tools (like bash) tend to detect the presence of an input stream, to differ between
interactive mode and a batch mode.
> If this is not possible, can also add a switch e.g. "--batch" or "-b" for "Batch mode".
> Note that the karaf "bin/shell" script already handles this quite nicely... by not hanging
after executing commands, and exits properly.
> BTW this should also be possible to do on karaf launcher itself (i.e. start Karaf, execute
command(s), then immediately shutdown the runtime).
