why /usr/bin/mailx /usr/bin/mail set the group to be that of the sender

why /usr/bin/mailx /usr/bin/mail set the group to be that of the sender

Post by Oon-Gil Pa » Wed, 15 Sep 1993 11:11:31



This is a probelm on sol2.2.
Hi, when there is no file for a user in /var/mail and a new mail arrives
and creates  the mailbox on /var/mail directory, the file permission mode
is set to be 0660(-rw-rw----) with the group id to be that of the sender.
So, anyone with the group id can read the mail box. why isn't it set to
be 0600(-rw-------) with the group id to be that of the mail recepient?
How can I fix this problem or is this a bug with the programs?

1. /usr/bin, /usr/local/bin, /sbin or /opt/bin, /var/opt/bin - I'm confused.

Hi all,

All these directories are for executable binary, right ?  How does one
decide which executable binary goes to which directory ?

/usr/bin : For what ?
/usr/local/bin:  for what ?
/sbin : ??
/opt/bin : ??
/var/opt/bin : ??

Is there any other /bin beside those above ?

Thanks

2. alias of df : capacity > 80%

3. /bin /usr/bin /usr/local/bin etc

4. pgcl-2.5.68-1

5. /usr/bin/ls /usr/ucb/ls /usr/local/bin/ls

6. Taking advantage of multiple CPUs?

7. Why does "cd /usr/////bin" = "cd /usr/bin"?

8. ethemes in Enlightenment

9. Why /usr/bin instead of /usr/local/bin for gnu stuff?

10. setting executable path to both /usr/local/bin/ & /usr/bin/

11. Why does /bin/login and /usr/bin/newgrp not have setuid bit set?

12. diff. between /usr/vac/bin/xlc & /usr/bin/xlc
