Open a shell for a an individual task

[Hennebold, Christoph]

Hi Adam, 

thank your for your reply, this exactly what I'm trying to do.

I have a server running a filesystem and simply hook up with my client to use its interfaces.
This is done with basic commands  like ls, open or mkdir, which the user can type in during runtime.

Best regards,
Christoph

I'm not sure I understand this correctly but is the question whether it
is possible to start an interactive program (which a 'shell' would be)?
Yes, a simple way is to ensure your shell has the 'log = L4.Env.log' in
its start sequence in ned. Then link against the libc_be_stdin library
which gives you a working getchar() (or use libreadline).
