- _e_c_h_o writes its arguments separated by blanks and terminated by a new-
- line (except when "-n" is specified, see below) on the standard output.
- It also understands C-like escape conventions; beware of conflicts with
- the shell's use of \\\\:
-
- \\\\bbbb backspace
- \\\\cccc print line without new-line
- \\\\ffff form-feed
- \\\\nnnn new-line
- \\\\rrrr carriage return
- \\\\tttt tab
- \\\\vvvv vertical tab
- \\\\\\\\ backslash
- \\\\0000_n where _n is the 8-bit character whose ASCII code is the 1-, 2-
- or 3-digit octal number representing that character.
-
- _e_c_h_o has two operating modes. By default, _e_c_h_o operates compatibly with
- certain earlier versions of System V _e_c_h_o. If the environment variable
- ____XXXXPPPPGGGG is defined, and has a numeric value greater than 0, _e_c_h_o operates in
- conformance with the X/Open XPG4 specifications. In this mode, when ----nnnn is
- specified, it is treated as a string, like any other arguments. In the
- backward compatibility mode, when ----nnnn is specified, it means "no new-
- line". The arguments will not be terminated by a new-line on the standard
- output.
-
- _e_c_h_o is useful for producing diagnostics in command files and for sending
- known data into a pipe.

- When representing an 8-bit character by using the escape convention \\\\0000_n,
- the _n must aaaallllwwwwaaaayyyyssss be preceded by the digit zero (0).
- For example, typing: eeeecccchhhhoooo ''''WWWWAAAARRRRNNNNIIIINNNNGGGG::::\\\\00007777'''' will print the phrase WWWWAAAARRRRNNNNIIIINNNNGGGG::::
- and sound the ``bell'' on your terminal. The use of single (or double)
- quotes (or two backslashes) is required to protect the ``\'' that
- precedes the ``07''.
- For the octal equivalents of each character, see ascii(5).
-
- echo is often a builtin to the shells, see the shell man pages for
- feature specific to each shell. This man page documents the executable
- program, not the builtin versions, although they are similar.
