and — logical AND of input values

and(bool) -> bool

The and aggregate function computes the logical AND over all of its input.

Anded value of simple sequence:

echo 'true false true' | super -z -c 'and(this)' -

false

Continuous AND of simple sequence:

echo 'true false true' | super -z -c 'yield and(this)' -

true
false
false

Unrecognized types are ignored and not coerced for truthiness:

echo 'true "foo" 0 false true' | super -z -c 'yield and(this)' -

true
true
true
false
false

AND of values grouped by key:

echo '{a:true,k:1} {a:true,k:1} {a:true,k:2} {a:false,k:2}' |
  super -z -c 'and(a) by k |> sort' -

{k:1,and:true}
{k:2,and:false}
