And now, will the real GNU echo please stand up?
An example of history repeating itself first as farce, then as tragedy.
<scarlatti 122 12:31 ~ >/bin/echo --help
Usage: /bin/echo OPTION... STRING...
Echo the STRING(s) to standard output.
-n do not output the trailing newline
-e enable interpretation of the backslash-escaped characters
-E disable interpretation of those sequences in STRINGs
--help display this help and exit (should be alone)
--version output version information and exit (should be alone)
Without -E, the following sequences are recognized and interpolated:
\NNN the character whose ASCII code is NNN (octal)
\a alert (BEL)
\c suppress trailing newline
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
