Unlike previous OSes, UNIX provided the pipe facility to allow you to combine the functionality of many small programs.
Ex. ls | grep ... | sort ... | more
Before that every command-line program had to support the full suite of additional functionality like search, filtering, paging, etc.
This UNIX/Pipe approach allowed for greater reuse and much less code.
This is explained and simulated in this video:
