What does the echo command do?

Echo, a fundamental command in computing, serves a pivotal role in outputting strings that are provided as inputs. This versatility extends across various operating system shells, showcasing its ubiquitous nature.

Frequently employed in shell scripts and batch files, echo facilitates the display of status messages on the screen or within computer files. Its simplicity belies its power, as it serves as a fundamental building block for more complex automation tasks.

The command's primary function is to echo back, or replicate, the input strings it receives. This straightforward action enables developers and system administrators to quickly and easily incorporate dynamic text into their scripts and programs.
