merge

Operator

  merge — combine parallel pipeline branches into a single, ordered output

Synopsis

( ... ) ( ...) | merge <expr> [asc|desc] [nulls {first|last}] [, <expr> [asc|desc] [nulls {first|last}] ...]]

Description

The merge operator merges inputs from multiple upstream branches of the pipeline into a single output. The order of values in the combined output is determined by the <expr> arguments, which act as sort expressions where the values from the upstream pipeline branches are forwarded based on these expressions.

Examples

Copy input to two pipeline branches and merge

fork 
  ( pass )
  ( pass )
| merge this
