ECHO(1V)                                                              ECHO(1V)



NAME
       echo - echo arguments to the standard output

SYNOPSIS
       echo [ -n ] [ argument ...  ]

SYSTEM V SYNOPSIS
       /usr/5bin/echo argument ...

AVAILABILITY
       The  System  V  version  of this command is available with the System V
       software installation option.  Refer  to  for  information  on  how  to
       install optional software.

DESCRIPTION
       echo  writes  its  arguments on the standard output.  Arguments must be
       separated by SPACE characters or TAB characters, and  terminated  by  a
       NEWLINE.

       echo  is  useful  for  producing  diagnostics in shell programs and for
       writing constant data on pipes.  If you  are  using  the  Bourne  shell
       (sh(1)), you can send diagnostics to the standard error file by typing:
              echo ...  >>&&2

SYSTEM V DESCRIPTION
       Note:  If  /usr/5bin  is ahead of /usr/bin in the Bourne shell's search
       path, its built-in echo command mimics the System V version of echo  as
       described here.

       echo  also  understands C -like escape conventions; beware of conflicts
       with the shell's use of `\':
              \b     BACKSPACE
              \c     Print line without NEWLINE
              \f     FORMFEED
              \n     NEWLINE
              \r     RETURN
              \t     TAB
              \v     vertical TAB
              \\     backslash
              \n     the 8-bit character whose ASCII code is the 1-, 2-, 3- or
                     4-digit octal number n.  The first digit must be zero.
OPTIONS
       -n     Do not add the NEWLINE to the output.
