echo(C)                         19 June 1992                         echo(C)


 Name

    echo - echo

 Syntax

    echo [ -n ] [ arg ] ...

 Description

    The echo command writes its arguments separated by blanks and terminated
    by a new-line on the standard output. The -n option prints a line without
    the new-line; this is the same as using the \c escape sequence.

    echo also understands 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

    \n    The 8-bit character whose ASCII code is a 1, 2 or 3-digit octal
          number.  In all cases, n must start with a zero.  For example:

          echo "\07"      Echoes <Ctrl>g.

          echo "\007"     Also echoes <Ctrl>g.

          echo "\065"     Echoes the number ``5''.

          echo "\0101"    Echoes the letter ``A''.

    The echo command is useful for producing diagnostics in command files and
    for sending known data into a pipe.

 Notes

    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''.

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

    An internal version of this command is provided by ksh(C) and may behave
    slightly differently; please refer to the ksh(C) entry for details.
