to_stdout

Writes events to standard output.

to_stdout

Description

The to_stdout operator writes events to standard output. Without a nested pipeline, to_stdout prints TQL by default. This is useful when using the tenzir executable as part of a shell script or command chain.

`{ … }`

An optional pipeline to transform the input before writing it to standard output. The pipeline receives the input of to_stdout and must produce bytes.

Use a writer such as write_ndjson, write_json, or write_tql when the input is events.

Omit the pipeline to print events as TQL.

Examples

Write events as NDJSON

from {x: 1}, {x: 2}
to_stdout {
  write_ndjson
}

{"x":1}
{"x":2}

Write events as TQL

from {x: "Hello World"}
to_stdout

{x: "Hello World"}
