NAME

echo − echo (print) arguments

SYNOPSIS

echo [ arg ] ... 

DESCRIPTION

Echo writes its arguments separated by blanks and terminated by a new-line on the standard output.  It also understands C-like escape conventions; beware of conflicts with the shell’s use of \:

\b backspace

\c print line without appending a 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 the 1-, 2-, 3- or 4-digit octal number n, whose first character must be a zero.

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

SEE ALSO

sh(1). 

NOTES

Berkeley echo differs from this implementation.  The former does not implement the backslash escapes.  However, the semantics of the \c escape can be obtained by using the -n option.  The echo command implemented as a built-in function of csh(1) follows the Berkeley semantics.

BUGS

No characters are printed after the first \c.  This is not normally a problem. 

INTERNATIONAL SUPPORT

8- and 16-bit data.
