What are other common echo command options?

In addition to the commonly used options -n, -e, and -E, here are a few more options that can be used with the echo command:

--help: Displays a help message with usage information for the echo command.
```
echo --help
```
--version: Displays the version information of the echo command.
```
echo --version
```
-c: This option is not standard across all implementations of echo, but in some versions, it can be used to specify that the output should be written to the console without any formatting.
-s: Similar to -c, this option may be available in some implementations to suppress output.

Note that the availability of these options can vary depending on the shell and the specific implementation of the echo command. Always refer to the manual page (man echo) for the most accurate information regarding options available in your environment.
