echo(1)                  USER COMMANDS                    echo(1)



NAME
     echo - echo arguments

SYNOPSIS
     echo [ arg ] ...
     echo [ -n ] [ arg ]

DESCRIPTION
     echo writes its arguments separated by blanks and terminated
     by a new-line on the standard output.

     The /usr/bin/sh version  understands  the  following  C-like
     escape conventions; beware of conflicts with the shell's use
     of \:

          \b   backspace
          \c   print line without new-line
          \f   form-feed
          \n   new-line
          \r   carriage return
          \t   tab
          \v   vertical tab
          \\   backslash
          \0n  where n is the 8-bit character whose ASCII code is
               the  1-,  2-  or 3-digit octal number representing
               that character.

     The following option is available to /usr/bin/sh users  only
     if  /usr/ucb  precedes  /usr/bin  in  the user's PATH. It is
     available to /usr/csh users, regardless of PATH:

          -n   Do not add the newline to the output.

     echo is useful for producing diagnostics in  command  files,
     for  sending  known data into a pipe, and for displaying the
     contents of environment variables.

SEE ALSO
     sh(1).

NOTES
     The -n option is a transition aid for BSD applications,  and
     may not be supported in future releases.

     When representing an 8-bit character  by  using  the  escape
     convention  \0n,  the n must always be preceded by the digit
     zero (0).

     For example, typing:   echo  'WARNING:\07'  will  print  the
     phrase  WARNING:   and  sound the ``bell'' on your terminal.
     The use of single (or double) quotes (or two backslashes) is
     required to protect the ``\'' that precedes the ``07''.



                                                                1

echo(1)                  USER COMMANDS                    echo(1)



     Following the \0, up to three digits are used in  construct-
     ing  the octal output character.  If, following the \0n, you
     want to echo additional digits that  are  not  part  of  the
     octal  representation, you must use the full 3-digit n.  For
     example, if you want to echo ``ESC  7''  you  must  use  the
     three  digits ``033'' rather than just the two digits ``33''
     after the \0.
        2 digits   Incorrect:   echo "\0337"  | od -xc
                   produces:    df0a                  (hex)
                                337                   (ascii)

        3 digits   Correct:     echo "\00337" | od -xc
                   produces:    lb37 0a00            (hex)
                                033 7                (ascii)

     For the octal equivalents of each character,  see  ascii(5),
