Autzoo.1052 net.v7bugs utzoo!henry Sat Oct 24 19:27:01 1981 shell mail checking Bill Reeves of Lucasfilm has found a subtle bug in the Bourne shell's mail checking: if the mailbox is temporarily nonexistent (some mail systems remove an empty mailbox), the shell can get a garbage mail date into its memory, which can effectively suppress mail checking thenceforth. The fix is like this, in main.c (line numbers are approximate): 139,140c139,141 < ANDF mailtime < THEN prs(mailmsg) --- > THEN > IF mailtime THEN prs(mailmsg) FI > mailtime=statb.st_mtime; 142d142 < mailtime=statb.st_mtime;
