Thanks for the reply. The ESC-ESC that you mentioned answers a part of my question. My understanding is that ESC-ESC just completes the command but it is not forward looking. For example, if I just want to see the contents of the /root directory without actually “cd”-ing into it, I cannot do it.
ls /root (Now if I press ESC-ESC it won’t show me the output)
The feature that I am talking about is the same which is there in all Linux Distributions and also on UNIX systems.
That feature is not available. It is most probably a feature of the shell ( bash maybe ), it should be possible to install bash under QNX6 ( never done it myself ).
Actually autocompletion will work, but not showing the possible values for autocompletion if there are more than one.
At least not in the default shell with default setup.
