Run Multiple Chained Commands On Input

Execute multiple commands in sequence on piped input using xargs.

Terminal

<arguments_source> | xargs sh -c "<command1> && <command2> | <command3>"

<arguments_source> | xargs sh -c "<command1> && <command2> | <command3>"

#!/bin/bash

# Run Multiple Chained Commands On Input
{{arguments_source}} | xargs sh -c "{{command1}} && {{command2}} | {{command3}}"

When To Use

When executing a series of actions that depend on the same input data stream.

Pro Tip

Use '&&' between commands to ensure each command only runs if the previous command was successful.
