echo - (BSD) echo arguments
/usr/local/heirloom/usr/ucb/echo [
argument ...]
Echo writes its
arguments separated by blanks and terminated by a
newline on the standard output.
Echo is useful for producing diagnostics in shell programs and for
writing constant data on pipes. To send diagnostics to the standard error
file, do `echo ... 1>&2'.
printf(1)
It is recommended for portability that
printf(1) is used instead of
echo if backslashes are to be printed or if the trailing newline is to
be omitted.
