Any ideas? I've had a glance through the source in /usr/src/usr.bin/biff/biff.c and it only tweaks on some bits in the perms of the tty you're login on: ... switch (argv[0][0]) { case 'n': if (chmod(name, sb.st_mode & ~(S_IXUSR | S_IXGRP)) < 0) err(2, "%s", name); break; case 'y': if (chmod(name, (sb.st_mode & ~(S_IXUSR | S_IXGRP)) | S_IXUSR) < 0) err(2, "%s", name); break; case 'b': if (chmod(name, (sb.st_mode & ~(S_IXUSR | S_IXGRP)) | S_IXGRP) < 0) err(2, "%s", name); break; default: usage(); } return (sb.st_mode & (S_IXUSR | S_IXGRP) ? 0 : 1); ... and then exits. The rest should depend on the login shell and its env var MAIL and/or MAIL_PATH. Said that, it does not do what I want because in many times my netbook is only booted, receives mails to /var/mail/guru and I'm only connected via SSH to it. matthias -- Matthias Apitz, ✉ guru@unixarea.de, http://www.unixarea.de/ +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub August 13, 1961: Better a wall than a war.
