Command substitution - how?


I am stuck at pretty simple thing:
How does one do command substitution in DO? I mean `` operator in Unixes.

Oh, and I mean- in commands.

What's an example of what you want to do?


For example rename current directory based on output of an external tool printed to stdout.

Opus can't do that directly. I'd recommend a button which does it via VBScript or similar.

This is actually possible to some degree, see:
