True(ish)

I've used something similar in a couple of my own projects.

The drawback for "preloading" the responses to an interactive stream like this 
is that neither ftp nor sftp include a way to determine whether or not the 
commands worked. Had your sftp session not been able to connect to localhost, 
or not been able to cd to /tmp, the "preloaded" command stream would have 
failed, but /appeared/ to have worked.

There /are/ (s)ftp clients that support scripting, and scripting languages 
(like perl and php, for instance) that support (s)ftp, so this potential flaw 
can be remedied.

OTOH, the OP has yet to explain what he meant, so perhaps we are going down 
the wrong path. I guess time will tell.  :-)
