> [Wiki](https://en.wikipedia.org/wiki/Pipeline_(Unix))  

> In Unix-like computer operating systems, a pipeline is a mechanism for inter-process communication using message passing. A pipeline is a set of processes chained together by their standard streams, so that the output text of each process (stdout) is passed directly as input (stdin) to the next one.

Use `tpack` to write Go applications that act as pipeline commands.

Employ channels, goroutines, regular expressions and more to build powerful concurrent workflows.

## Usage

See the ETL workflow in the [examples](examples) folder.

```go

package main

import "github.com/reugn/tpack"

func main() {

	tpack.NewPackerStd(tpack.NewProcessor(

		doETL,

	)).Execute()

}

```

Test command

```sh

cat input.txt | go run *.go 2>/dev/null | wc -l

```
