To produce output from shell scripts.

echo prints each argument to standard output, separated by a
single space
and terminated by a newline. It interprets escape sequences
within each
string that represent special characters and also control its
behavior.

Historical differences in behavior among Unix variants make it
difficult
to use echo portably for all but the simplest kinds of output.
