UNIX commands are designed to be simple in the first place; they basically do one task per command. To make a more powerful sequence, just put (or pipe) several commands together in a sequence.
The ability to use many of the commands in different scenarios just by the command sequence is very powerful; the individual commands do not have to be that powerful or complex, but the result of using several of them in a row makes for a very powerful system.

the unix phylosophy is "do a single job correctly" . due to this the authors / creatorscreated unix commands simpler. to do complex tasks the simpler commands are combined. for example head command is used to displasy the top ten or required number of lines from a file "file" tail commandis used to displasy the lastten or required number of lines from a file "file" but if i require to lines from 3rd line to 10th line i does not have the command to do this i combine head & tail commands head -10 file | tail -7 by rami reddy
A single keystroke or command that initiates a longer predetermined series of keystrokes or commands is called a "macro." Macros are commonly used in software applications to automate repetitive tasks, enhancing efficiency and productivity by executing complex commands with a single action.

Commands tell computers what tasks they should perform. Software installed on computers provide the commands users need to complete tasks on computers.
In most cases many simple tasks equal massive tasks. Computers can do both simple and (given enough power) can also do massive tasks
Computers operate by processing input from users and executing commands through a series of electrical signals. They require energy, typically from electrical sources, to power their components like the CPU, memory, and storage devices. The responses to user commands are facilitated by software algorithms, which translate inputs into actions, allowing users to interact with the system effectively. This interaction is fundamental to computing, enabling tasks ranging from simple calculations to complex data processing.
Rube Goldberg was an award winning cartoonist. Many of his drawings depicted incredibly complex machines to carry out very simple tasks.
A set of commands that automates a complex task is typically referred to as a "script" or "automation script." These scripts can be written in various programming or scripting languages, such as Python, Bash, or PowerShell, and are designed to execute a series of instructions automatically without manual intervention. By using scripts, repetitive tasks can be streamlined, reducing the potential for human error and increasing efficiency.
