Description Norbert Plött CLA 2006-10-31 03:44:56 EST 
After connecting via SSH and opening a shell I can enter commands (which is good). But there are issues with the linebreaks. Like so:

==================snip======================
pn3484@nb14520d:~> 
echo hello
hello
pn3484@nb14520d:~> 
pn3484@nb14520d:~> 
==================snap======================

1) The command "echo hello" should appear on the same line as the prompt.
2) After the "hello" output two prompts are displayed.

Is this maybe because I am on Windows which does CR/LF and both are interpreted as LF by the Linux target?

Comment 1 Martin Oberhuber CLA 2006-10-31 07:24:24 EST 
The double command prompt is due to the way how the remote current directory is queried and displayed in an RSE-compatible prompt: the SshServiceCommandShell issues an extra "; echo `pwd`>" command after every normal given command. Because of that, two normal prompts are shown on ssh.

I see two possibilities for fixing this:
a) Once environment variable setup is fully integrated, we can set $PS1=$PWD> and thus avoid the extra prompting. That's the way how dstore handles this.
b) We could try to match what the remote system sends as prompt, and suppress printing it.

I like approach (a) better. 
To be done after 1.0.

I like approach (b) better. The user's chosen environment should not be modified because of the special needs of RSE. 

Or, (c), could the RSE issue it's echo `pwd` as a separate command and suppress the output until after pwd has completed?

> To be done after 1.0.

Sure. This is just "not nice", a minor defect.

Deferring shell (RSE Commandview) related bugs since ITerminalService is more interesting for WR now
