ECHO(1) INTERACTIVE UNIX System ECHO(1)
NAME
echo - echo arguments
SYNOPSIS
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; 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
\0n where n is the 8-bit character whose ASCII code is
the 1-, 2- or 3-digit octal number representing
that character.
The echo command is useful for producing diagnostics in com-
mand files and for sending known data into a pipe.

sh(1).
CAVEATS
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) in
the INTERACTIVE SDS Guide and Programmer's Reference Manual.
