ksh -x pr.sh
ksh -n pr.sh
nhoup ksh pr.sh &
nohup ksh pr.sh &
i want the output like this
Tue Mar 14 17:18:57 GMT 2006 vi pr.sh HOSTNAME
is it possible sir ???? (3 Replies)
I need a command that will list all the users and their last login date & time. I was trying the last command and the who command, but can't get exactly what I need.
I just need the output to be user name and last login date .
Thanks for your help! (3 Replies)
As a system administrator. sometimes we see the users are trying some commands dangerous for the system health and remove them from their individual coomand history file.
How it is possible to enforce that the normal usres will will not be able to modify the history.
Thanks in advance.

i need to find out following ways to show out put in a shell script when the user selects that option in a case statement. I have the case statement already started just need to find out how to read the following:

Hi all,
My need is :

Can anyone tell this:
If two users are logged into the same server from different locations. Is there a way to see the history command of the other user? I tried the history command, but it is showing me only the commands I used.
Thanks in advance for your help.

bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
