ECHO(1)
NAME
echo − echo arguments
USAGE
echo [ −n ] [ arg ] ...
DESCRIPTION
Echo writes its arguments separated by blanks and terminated by a newline on the standard output. If you specify the −n option, echo adds no newline to the output.
Echo is useful for producing diagnostics in Shell programs and for writing constant data on pipes. You may send diagnostics to the standard error file by specifying the following (in the Bourne Shell):
echo ... 1>&2
