ECHO(1)                                                   ECHO(1)

          echo - echo arguments

          echo [ -n ] [ arg ] ...

          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'.
