NAME
echo - echo arguments

SYNOPSIS
echo [ -n ] [ arg ] ...

DESCRIPTION
Echo writes its arguments separated by blanks and terminated by a
newline on the standard output. If the flag -n is used, no newline
is added to the output.

Echo is useful for producing diagnostics in shell programs and for
writing constant data on pipes. To send diagnostics to the
standard error file, do ‘echo ... 1>&2’.
