The 2nd and 3rd examples make no sense to me.
echo '{"a": 1, "b": 2}' | jaq 'add'

Construct an array from an object in two ways and show that they are equal:
$ echo '{"a": 1, "b": 2}' | jaq '[.a, .b] == [.[]]'

I agree, it wouldn't be the best to handle all json edge cases, but it would be a super easy way to quickly get data from a big chunk of simple json and you could just use subqueries or query chaining for nested results. For anyone who hasn't used powershell, this is the difference I'm talking about. I would not be able to write either of these without looking up the syntax. But knowing very little about powershell,…
On the other hand, I find the bash one clear and concise. That PowerShell example is so verbose, it'd drive me crazy to do any sort of complex manipulation this way! To each their own, I guess.
If all I was doing is writing code, I agree. But like most developers, I think I read a lot more code than I write.

Nice find. I think I'll try it out. Although I was hoping for a real SQL type experience. I don't understand why no one just copies SQL so I can write a query like "SELECT * FROM $json WHERE x>1". Everyone seems to want to invent their own new esoteric symbolic query language as if everything they do is a game of code golf. I really wish everyone would move away from this old Unix mentality of extremely concise, yet…
do more like the power shell way I just checked the GitHub page [1] for Microsoft PowerShell. It looks written in C# and available on Win32/MacOS/Linux, where DotNet is now supported. Do you use PowerShell only on Win32 or other platforms also? Everyone seems to want to invent their own new esoteric symbolic query language Can you give an example of something that PS can do that is built-in for text processing, inste…
By "the powershell way" I don't mean actually using powershell. I just mean using verbose, descriptive commands that one can easily understand what it does without having a working knowledge of the scripting language.

What might be confusing is that iterating an object iterates its values. add is defined something like this: def add: reduce .[] as $n (0; . + $n)
