operator | method

Script operator |(
  1. Object other

Pipes this script's stdout into other's stdin.

The other must be either a Script or an object that can be converted into a script using the Script.fromByteTransformer and Script.fromLineTransformer constructors.

Returns a new Script whose stdin comes from this and whose stdout and stderr come from other.

This behaves like a Bash pipeline with set -o pipefail: if either this or other exits with a non-zero exit code, the returned script will fail, but it will only exit once both component scripts have exited. If both exit with errors, other's exit code will be used.

This doesn't add any special handling for this's stderr.

See also pipe, which provides a syntax for creating a pipeline with many scripts at once.


Script operator |(Object other) => Script.pipeline([this, other]);
