Question for anyone that might be able to help:
My objective is to eheck if a file (a source file) exists in a directory. If it does then, I'd like to call an application (Informatica ETL file...not necessary to know) to run a program which extracts data and loads it into multiple targets.

Status quo is, within a web application, which is coded completely in php (not by me, I dont know php), I have to fill out several fields, and execute it manually by clicking the "go" button in my browser, several times a day.
Thats because:

Hello everyone,
I have two types of files in a directory:
*.txt
*.info
I have a perl script that uses these two files as arguments, and produces a result file:

Hi All,
I have one query, I managed to run script with user inputs through command line or with 1 file.
But I need to read a txt file/xml file in which user can mention multiple sets of answers and script should run for each set till it reach the EOF.
Thanks in advance

I have two scripts which I'm tying to run one after the other- this is what I've tried:
00 14 * * * /path/one.sh && /path/two.sh
I've also tried putting each script on a different line:
00 14 * * * /path/one.sh
00 14 * * * /path/two.sh
Can this be done? (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.
