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'.
