Run Command On Input Lines

Runs a command on each line of a specified input source, facilitating batch processing.

Terminal

<arguments_source> | xe <command>

<arguments_source> | xe <command>

#!/bin/bash

# Run Command On Input Lines
{{arguments_source}} | xe {{command}}

When To Use

When processing a file line-by-line in automation scripts or large-scale batch jobs.

Pro Tip

Defining input file sizes larger than memory limits may force line-by-line streaming instead of direct loading.
