- usage: echo [-ne] [args...]
-
- Write each argument to stdout, with one space between each, followed
- by a newline.
-
- -n No trailing newline.
- -e Process the following escape sequences:
- \\ backslash
- \0NNN octal values (1 to 3 digits)
- \a alert (beep/flash)
- \b backspace
- \c stop output here (avoids trailing newline)
- \f form feed
- \n newline
- \r carriage return
- \t horizontal tab
- \v vertical tab
- \xHH hexadecimal values (1 to 2 digits)
