Hi,
i have a problem with turning a job into backgrund.
When i enter this at the shell:
spice -b darlington.cir -r output.raw > screenout.tmp &
and then let me show the currently running jobs, i get the following output:

Hi there,
I'm quite new to UNIX for programming. I have a script that does this:

However, when I start my script, I want my script to start logging in the file in the background, so I can continue working on... (1 Reply)
i need to execute 5 jobs at a time in background and need to get the exit status of all the jobs i wrote small script below , i'm not sure this is right way to do it.any ideas please help.

Reposting, as it got lost during the database backup. :(
Via a shell script a spawn 3 background jobs namely a, b & c.
These will take different times to complete.
I want to print a different message on completion of each.
How can i find out when each one has completed independently.

Hi All,
I have some script that run some commands and send results to my email. I want to run same script on mulitiple servers. How can I do that. I know there is an option "ssh". But I'm not quite sure how to use it in the script.

We had a generic process where the jobs are scheduled to run sequentially and in background. We are noticing the problems with the background jobs.

Hi All,
Can someone help me in knowing the exact difference between nohup and &.
The definition is quite clear but i only want to know if i run my job using & and in between i hung up my terminal. (10 Replies)
I have multiple jobs and each job dependent on other job.
Each Job generates a log and If job completed successfully log file end's with JOB ENDED SUCCESSFULLY message and if it failed then it will end with JOB ENDED with FAILURE.
I need an help how to start.
Attaching the JOB dependency... (3 Replies)

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.
