Hello. In English this makes me think of the phrase “dog shit”. Not sure if that’s intentional or not.

This is very interesting, but I'm wondering how it compares to just using a dynamic language like Python or Ruby for the same tasks. Curious how the line count to express the same tasks would come out.

English is my third language and I can confirm I didn't even think about this

There is a lot of stuff for Python which follows the "express computation as a dag" approach, especially Apache Airflow

That's what I think when I hear "bash".

This would have been great 10-20 years ago, or even at the coining of Unix pipes. By today's standards, however, the syntax feels clunky and dated. I'd like to see contemporary shells like nushell and elvish copy these ideas, with attribution of course, in a more modern way. That is the best way I can see to honor this stagnant project: https://github.com/dspinellis/dgsh
