This command is most commonly used in administration scripts to inform the user during execution.

The `-n` option will not return to the line after displaying the text (which is the default behavior of the command).
The `-n` option indicates no newline output string (by default, newline output string).

```bash
shell > echo -n "123";echo "456"
123456

shell > echo "123";echo "456"
123
456
```
