=============================
Synopsis
--------
.. synopsis::
echo [OPTIONS] [STRING]
Description
-----------

**-n**
Do not output a newline.
**-s**

Unlike other shells, this echo accepts ``--`` to signal the end of the options.

If ``-e`` is used, the following sequences are recognized:
- ``\`` backslash
- ``\a`` alert (BEL)
- ``\b`` backspace
- ``\c`` produce no further output
- ``\e`` escape
- ``\f`` form feed
- ``\n`` new line
- ``\r`` carriage return
- ``\t`` horizontal tab
- ``\v`` vertical tab
- ``\0NNN`` byte with octal value NNN (1 to 3 digits)
- ``\xHH`` byte with hexadecimal value HH (1 to 2 digits)

> echo -e 'Top\nBottom'
