If you deal with multiple instances of Caché / Ensemble / HealthShare and sometimes have to work at the Terminal command prompt, did you know that you can easily add extra information to that prompt which may help prevent you running a command on the wrong instance?
The format of the command prompt is controlled by the TerminalPrompt setting in the [Startup] section of the CPF but it is normally manipulated via Portal. The documentation is
[here](http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=RCPF_TerminalPrompt).
The default prompt looks like this:
USER>
USER>; TerminalPrompt="8,2"
The 2 is what provides the namespace name. Most of the time the 8 adds nothing, but you can see its effect by starting a transaction or two, then ending them:
USER>tstart
TL1:USER>tstart
TL2:USER>tcommit
TL1:USER>tcommit
USER>
When working with multiple instances, perhaps across different servers, setting TerminalPrompt="8,1,3,2" may be useful:
Node: TIN, Instance: ENS171
TIN:ENS171:USER>
TIN:ENS171:USER>; TerminalPrompt="8,1,3,2"
