echo(1) USER COMMANDS echo(1)
NAME
echo - echo arguments
SYNOPSIS
/usr/ucb/echo [ arg ] ...
/usr/ucb/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 preceds /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
and for sending known data into a pipe.

NOTES
The -n option is a transition aid for BSD applications, and
may not be supported in future releases.
The 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(5),
