How do I dynamically set up an array. Below is my code
Here, I want to set values in the array "${ecomm_srvr[$j]}" into ecomm_task_limit upon each iteration. Finally I want to display all the values in the new array "ecomm_task_limit" after all the iterations are complete.
I need to do something like this:
KEYS=
for key in $KEYS
do
echo $key
done
The KEYS are static values in my script, I'm just having trouble with setting them as separate values.

Hi,
I am trying to name a set of arrays dynamically named as @array_$i (The $i will mean that I obtain a set of arrays called:
@array_1
@array_2
@array_3 etc.
i tried various methods like
@array_$i
@{array_$i}
etc.
any ways to do this
Thanks (4 Replies)
hi,
iam getting error when i assign a variable to an array of more that 315 character in length
set -A array <variable>
<variable> value is 000001 000002 and up to 000045
it is giving error as
"The specified subscript cannot be greater than 1024."
can any one help me to solve this (2 Replies)

Hi all,
I am fairly new to unix scripting and will like to know how to dynamically set the name of an environment variable to be used.
We have a .env file where we defined the names and locations of data files, trigger files, directories .... etc

I'm working in a linux server where wrappers are executed by multiple users of different groups. The log and output files are created with 554 permissions by default. This is stopping other users to run the wrappers unless the log and output files are deleted or given 777 permission. Setting SUID... (1 Reply)

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.
915 of 1612581 (0.057%)
