Hi Dave, thanks for the reply. I'm just running a script containing a few command for collecting statistics and health of the server and someone told me if i don't add /dev/null 2>&1 entry . The system might crash due to mail queue.
honestly I don't get it . That's why I'm asking. I'm looking for a method/tricks to disable crontab from sending mail. If you know how to do it. Pls show me ?

I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"... (1 Reply)

BIFF(1) BSD General Commands Manual BIFF(1)
NAME
biff -- be notified if mail arrives and who it is from
SYNOPSIS
biff [ny]
DESCRIPTION
Biff informs the system whether you want to be notified when mail arrives during the current terminal session.
Options supported by biff:
n Disables notification.
y Enables notification.
When mail notification is enabled, the header and first few lines of the message will be printed on your screen whenever mail arrives. A
``biff y'' command is often included in the file .login or .profile to be executed at each login.
Biff operates asynchronously via the comsat(8) service. If that service is not enabled, biff will not do anything. In that case, or for syn-
chronous notification, use the MAIL variable of sh(1) or the mail variable of csh(1).
SEE ALSO
csh(1), mail(1), sh(1), comsat(8)
HISTORY
The biff command appeared in 4.0BSD.
BUGS
su(1), and biff don't seem to get on too well. This is probably due to the tty still being owned by the person using su. This can result in
``Permission denied'' messages when attempting to change the biff status of your session.
Please report bugs to netbug@ftp.uk.linux.org including diffs/patches, compiler error logs or as complete a bug report as is possible.
