Pipe (Unix)
A mechanism that connects the output of one process directly to the input of another. In automation philosophy, every step is a pipe data flows through a series of transformations from trigger to final output, each step adding value.
Expert insight
The Unix pipe philosophy, small tools each doing one thing well, chained together, maps directly onto good workflow design: a chain of single-purpose steps is easier to debug and reuse than one large step trying to do several things at once, the same principle that makes composable command-line tools powerful.
In a real workflow
In a shell, "cat orders.csv | grep paid | wc -l" chains commands, the same idea as chaining workflow steps.
Common mistakes
- Long pipes that are hard to debug.
- Ignoring errors in the middle of a pipe.
Complexity level
Requires some familiarity with automation concepts.
