When I use this command I get an output of some numbers
cat ac.20070511 | cut -d" " -f19
Is there any way for me to display only the numbers that are greater than 1000 but not all the numbers in the ouput.
Can any one help me with this. :) (8 Replies)
Hi,

Hi All,
I want a shell script which can display the file with in the date range.
For Example I have 15 files with the following format
abc_01-01-2009.txt to abc_15-01-2009.txt.
Now I want to have the files between 4th of jan to 12th files.
How can I acheive this.

Hi All,
I have a requirement to display all the dates within the provided (through user input) date range.
For eg: If I enter 28012009 (as From date in the format 'DDMMYYYY') and 02022009(as To date in the format 'DDMMYYYY'), the output should be all dates occuring between the from and to... (11 Replies)

Gents,
It is possible to generate a range of values according to column 1 and count the total of rows in the range.
example
input
15.3
15.5
15.8
15.9
16.0
16.1
16.8
17.0
17.5
18.0
output desired
15.0 - 15.9 = 4 (10 Replies)
My script reads all the log files in a directory, the user would enter a range and the script would only display the files within those range. Here's my code:
#!/bin/bash
LOG_FILES=("Sandbox/logs/*")
for file in ${LOG_FILES}; do echo $file; done
-------------
for i in $(seq $1 $2); do... (1 Reply)

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.
