I can do an automated FTP transfer of a list of files by including the appropriate list of commands in a file, called f, and typing (in csh) ftp remotehost < f. FTP then prompts me for my password before reading the commands from f (my username is in the .netrc file, but not my password). This is just what I want, but why does it work? How does FTP know not to look in f for my password? Lee Phillips phillips@cmf.nrl.navy.mil phillips@fozzie.nrl.navy.mil phillips@lcp.nrl.navy.mil

Ftp, like most programs that prompt for password, opens /dev/tty, flushes input from it, and then reads the password from it, rather than reading the password from stdin. In fact, it probably uses the getpass(3) library function. -- Jonathan Kamens USnail: MIT Project Athena 11 Ashford Terrace jik@Athena.MIT.EDU Allston, MA 02134 Office: 617-253-8085 Home: 617-782-0710
