xargs is a unix command for assigning various inputs to different other unix commands.
The Natural Function Connector
This command/program is particularly useful, and relevant to programming in general, because it is a way to redirect inputs from data pipes. In other words, it is a bridge between input sources and any chosen programs that can be run at the Unix command line. While using this instruction, I realized that xargs is a way to help users experience interactive functional programming. Similar impression can be attained by watching people writing CSS (2D) or using Geometry Node (3D) in Blender.
Executing one line at a time
To execute commands for each of the line feed, use the following option:-n 1. For example:
ls | xargs -n 1 -i echo {}
Note that one must supply the -i option, so that {} can become the placeholder for content piped from the previous process.
Accepting special separators=
In certain cases, when the input data embeds separators, one needs to turn on the -0 option. For example:
ls | xargs -0 -n 1 cp {} /targetDirectory
