"get the logs" means that isn't it that after executing the command
I want to get only logs starting from yesterday (24hrs earlier) up to the current system time the script has been executed.
example if today is Dec 19 15:00:00 and then I executed the script, it will give an output of the logs starting from Dec 18 15:00:00 up to Dec 19 15:00:00.
Hello!
I'm using a perl script which calls the time and
date from a remote server using the line
/bin/date -
What is needed in this line to
reduce the output time
5 hours?

Hi all,
I would like to capture the file contents every 3 hours. I will put the schedule inside crontab, how to get only incremental contents from the last 3 hours?
Thanks. (4 Replies)
Hi,
I generated an Oracle schema DDL script file using the show=y option of the Oracle import utility but the file that it generates needs a little more formating before we can run this as simple DDL comands to generate the schema at Target using the script file.Here is the simplified output of...

Hi again:
I have this code which gives an large output(several screens), and I want to display on screen at a time (like more does)....how can I do this?

Hi
we are calling kill -9 $pid command from bash script it gives below output, but we need to hide the output. i tried /dev/null but ni luck. is there any alternate way to schive this.

bup-margin
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.
