SYNTAX
echo [ arg ] ...
DESCRIPTION
Echo writes its arguments separated by blanks and terminated by a
new-line on the standard output. It also understands C-like
escape conventions; beware of conflicts with the shell's use of
\. Arguments are as follows:
\b Backspace
\c Print line without new-line
\f Form-feed
\n New-line
\r Carriage return
\t Tab
\\ Backslash
\n The 8-bit character whose ASCII code is the 1-, 2- or
3-digit octal number n, which must start with a zero.
\v Vertical tab
Echo is useful for producing diagnostics in command files and for
sending known data into a pipe.

EXAMPLES
$ echo Hello World
Prints the string "Hello World" on the standard output.
$ echo *
Prints the names of the files and subdirectories in the current
working directory. This output is similar to that of ls(1), but
the file and directory names are listed in one long line. It is
usually quicker than ls(1).
$ if test ! -r book
