#Terminal

When I build docker containers my build log usually looks like this:

#924.94

Is there any way to record commands? Currently I need to add:

But it would be way better if I could just see what's being executed.

This article will introduce you to the concept of virtual environments in Python, which are essential for managing dependencies and isolating project from the OS.

What is a Virtual Environment?

A virtual environment is a folder that contains :

• A specific version of Python
• At start an empty site-packages directory

Virtual environments will help you to isolate your project from the OS Python installation and from other projects.

How to use it?

Recent versions of IRIS come with Lite Terminal available from VSCode. It's a websocket server, with JSON messaging. Here's how to connect to it from Python:

importimportimport{

Running it produces the following output:

{

To debug the connection set  to 1, all communication would be logged to the same global.

I was trying to see if we could connect to another Server, we use to execute external scripts using %Net.SSH.Session.

TESTCLIN>set##class

How can I see what the SSH error was in the callback?

Access IRIS Terminal Session using WebTerminal. I noticed that the $P or $PRINCIPAL system variable is defined as //./nul

When logging into Terminal via Management Portal, $P = |TRM||$J

Because of this, we cannot get into Programmers Mode via ^%SYS.PMODE

Any ideas?

Hi,

When we open a terminal in IRIS, we are entering the ObjectScript shell. Within this shell, we can execute IRIS commands, such as:

In other words, the ObjectScript command is executed in the current shell. But it's always good to remember that IRIS has other shells

• SQL
• Python
• TSQL
• MDX

One very interesting aspect is shortcuts. We can access these shells through their calls or via shortcuts, as shown in the table below:

Can someone help me understand what type of user error (?) is going on here please?

One one system, I write out a group of $c() values and get the expected results:

USER>for i=250:1:260 { write i," ", $c(i),! }

I'm working with IRIS for Health. I need to abort all messages currently in the queue via the command line (IRIS terminal). is there any easy way?

Hello, how are you?

First of all thanks for your time reading this question.

We are investigating how to validate the indexes of a global. We have read:

https://docs.intersystems.com/irisforhealth20251/csp/docbook/DocBook.UI…

And:

https://docs.intersystems.com/irisforhealth20251/csp/documatic/%25CSP.D…

We want to validate the inxedes of the global titled "Ens.Util.LogD". We have executed on the ObjectScript terminal, on the desired namespace:

ESBSSCC>set tSC = $SYSTEM.OBJ.

Are you curious about how to run Python scripts directly in your InterSystems IRIS or Caché terminal? 🤔 Good news it's easy! 😆 IRIS supports Embedded Python, allowing you to use Python interactively within its terminal environment. 

How to access the Python Shell?

To launch the Python shell from the IRIS terminal, simply run the following command:

do##class%SYS.Python

This opens an interactive Python shell inside the IRIS terminal. From here, you can write and run Python code just as you would in a normal Python environment.

Hello Community
I was running code in the terminal and attempted to interrupt its execution. During that process, I encountered an application error with a log entry dated 01/06/1841, the date seems unusual.

Error <INTERRUPT>ErrST+6^%ETN occurred within %ETN itself. Detailed information cannot be logged.
