Parser Reference: Arrow 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.

-> differs from | in the interactive terminal where it produces different autocompletion suggestion. It returns a list of “methods”. That is, commands that are known to support the output type of the previous command. -> helps with the discovery of commandline tools.

In shell scripts, -> and | can be used interchangeably.

Examples

» out: Hello, world! -> regexp: s/world/Earth/
Hello, Earth!

» out: Hello, world!->regexp: s/world/Earth/
Hello, Earth!

In following 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!
