capture the output of a bash command

[nickkaranatsios]

Is it possible to capture the output of a bash command and store it in a pkl variable. For example str = "date '%s'"
I guess is it possible to run a bash command from pkl.
Thank you in advance.

It's not possible to do this as you've described, but you may be able to use a prop: resource in this specific case.

In your Pkl module:

str = read("prop:timestamp")

Then when evaluating:

pkl eval path/to/module.pkl -p timestamp=$(date %s)

Thanks for your reply I would try your suggestion.
