Adding the corresponding values for every 5th consecutive numbers
Dear All,
I have a file which is as follows:
Input File:
Expected Output:
Logic: The 1st column is printing every 5th number in the consecutive order(does not matter if it is not present in the input file). But it starts with the 1st number of the Column 1 and then prints every 5th number.
The second column prints the addition of all the 5 numbers. For example, 232 is not present, therefore we consider 0 corresponding to 232.
I am new in the field and would appreciate tour help.
I have a text file in the following format
....
START
1,1
2,1

Hi,
I have a file like this
A Bob
A Sam
A John
B David
C Paul
C Sandra
If the consecutive field values in column one is same, then concatenate the corresponding strings.
So, I need an output like this,
A Bob_Sam_John
B David
C Paul_Sandra

I have this code and I want to get the first two consecutive distances (obtained by calling GET_TH(IT, 'DIST', DIST) at index IT, the result stored in DIST) for which (ITFLG(IT) .NE. 1). L_FIRST get the first DIST for which ITFLG(IT) .NE. 1. Getting a bit confused on how to achieve this.

Hi all.
I have a directory which contains files that can be versioned. All the files are named according to a pattern like this:
TEXTSTRING1-001.EXTENSION
TEXTSTRING2-001.EXTENSION
TEXTSTRING3-001.EXTENSION
...
TEXTSTRINGn-001.EXTENSION
If a file is versioned, a file called

Hi,
I have an input file of the following style
input.txt
The 4000 at the end indicates the total no. of columns in that row.
I would like to replace all -1s with consecutive 1 and 2 and print the whole line again.
So, the output would be
output.txt
Thanks in advance. (7 Replies)

Hi all,
I have two (2) sets of files that are based on some snapshots of database that I want to merge and insert any missing sequential number.
Below are example representation of these files:

Hi,
In an ideal scenario, I will have a listing of db transaction log that gets copied to a DR site and if I have them all, they will be numbered consecutively like below.
1_79811_01234567.arc
1_79812_01234567.arc
1_79813_01234567.arc

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.
