Parser Reference: POSIX Pipe (|) Token

Pipes STDOUT from the left hand command to STDIN of the right hand command

Description

This token behaves much like pipe would in Bash or similar shells. It passes STDOUT along the pipeline while merging STDERR stream with the parents STDERR stream.

It can be used interchangeably with the arrow pipe, ->, in shell scripts.

Examples

» out: Hello, world! | regexp: s/world/Earth/
Hello, Earth!

» out: Hello, world!|regexp: s/world/Earth/
Hello, Earth!

In this example the first command is writing to STDERR rather than STDOUT so Hello, world! doesn't get pipelined and thus isn't affected by regexp:

» err: Hello, world! | regexp: s/world/Earth/
Hello, world!
