That means: on Black Friday, your hard drive will get wiped out.

==> (on 13th and Friday) 23:59, /wipe.disk will be running________________________________________If the 13'th Day of the month is Friday, the job will run. (week day starts from Sunday day 1).

in /etc/system set abort_enable=0 will disable STOP-A ________________________________________There are several ways to disable "STOP-A"
(1)Edit the /etc/default/kbd file
KEYBOARD_ABORT=disable
(2)Use the "kbd -a disable" command
(3) Edit /etc/system file
set abort_enable = 0

Just Type in the following command at prompt#ifconfig -a.That shall give the LAN Cards as well as total Physical and Logical IP Addresses

piping:- sending the output of a command to the input of another is called piping.

some examples are:

$cal | wc

will output total line's,word's and character's

$cal | wc | wc

will output total line's,word's and character's

A unix pipe provides a one-way flow of data.


For example, if a Unix users issues the command
$who | sort |lpr
then the Unix shell would create three processes with two pipes between them:

A pipe can be explicitly created in Unix using the pipe system call. Two file descriptors are returned--fildes[0] and fildes[1], and they are both open for reading and writing. A read from fildes[0] accesses the data written to fildes[1] on a first-in-first-out (FIFO) basis and a read from fildes[1] accesses the data written to fildes[0] also on a FIFO basis.

When a pipe is used in a Unix command line, the first process is assumed to be writing to stdout and the second is assumed to be reading from stdin. So, it is common practice to assign the pipe write device descriptor to stdout in the first process and assign the pipe read device descriptor to stdin in the second process. This is elaborated below in the discussion of multiple command pipelines.

/etc/skel

nfsd
mountd
lockd
statd
nfslogd

These five daemons will be in NFS server.

statd and lockd will be in NFS client too.

stop+A

/etc/shadow

SUNWadm

You have to use the option "d" along with th patchadd commnad.
patchadd –d

The UMASK value for bourne and korn shell users can be modified system wide by editing the "umask" entry in the "/etc/profile" file. To change the default UMASK for the C shell, modify the UMASK variable in "/etc/default/login" file.

name & save

enable

spray

/etc/named.conf

/etc/profile
