SYNOPSIS

       echo [argument ...]

DESCRIPTION

       Echo  writes its arguments separated by blanks and terminated by a new-
       line on the standard 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'.

       The following escapes sequences are recognized in the arguments:

       \a     Prints   an   alert    character    (/usr/5bin/posix/echo    and
              /usr/5bin/posix2001/echo only).

       \b     Prints a backspace character.

       \c     Causes the command to return immediately.  Any following charac-
              ters are ignored, and the terminating newline is not printed.

       \f     Prints a formfeed character.

       \n     Prints a newline character.

       \r     Prints a carriage-return character.

       \t     Prints a tabulator character.

       \v     Prints a vertical tabulator character.

       \\     Prints a backslash character.

       \0nnn  Prints the character (byte) with octal value nnn.

ENVIRONMENT VARIABLES

       LANG, LC_ALL
              See locale(7).

       LC_CTYPE
              Determines the scope of backslash as an escape character.

       SYSV3  If this variable is set and the first argument is -n, the termi-
              nating newline is not printed.

SEE ALSO

       printf(1)

NOTES

       It  is  recommended  for  portability that printf(1) is used instead of
       echo if backslashes are to be printed or if the trailing newline is  to
       be omitted.
