I'm no expert, but it seems like what you want is the `triggers` parameter? You can set it to something like `timestamp.toString()` so that it triggers and `update` on each run. I.E.

```const myCommand = new command.local.Command("my-command", {
    create: "echo 'Hello, Pulumi!'",
    // Use the timestamp as the working directory
    // This effectively forces the Command to run on every `pulumi up` since
    // the `triggers` argument will be different every time
    triggers: [timestamp.toString()],
});```

Ah, thanks Alex,.. that would definitely have the effect of what I want do.  That's going to effectively "recreate" that command every time?  so I wonder what `update`is really that useful for?

Yes, I believe so. I suppose `update` can be useful for things like when changing the command being run (for example, adding an environment variable?)

Cool; thanks for the insight. I'll play around with it.

I believe if you have an update script it will run instead of the create script whenever the command is triggered to run again (whether it’s from a trigger or from the script(s) being changed)

if you have a complex script that you keep changing over the lifetime of running deployments it ends up being a bit clunky (you’ll have to keep modifying both create and update in order to have both working existing deployments and a working initial create script), but it is possible at least

I see.  Yah, the script itself is idempotent (e.g. it runs DB migration tools).. so I just need it to run every time.  For now I just went with Alex's suggestion and have it always running against an updated timestamp.

You can also use <https://www.pulumi.com/registry/packages/command/api-docs/local/run/> to run a command every time.
