The Tricks

Getting the password to the ftp server without having the ftp client program read the password from /dev/tty requires two tricks:

2. Use the ftp client program command quote to send user ID and password to the ftp server.
3. The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty.
4. /dev/tty helps output displayed to the  (terminal)
