I try to run a script as background job.
script:
#!/usr/bin/csh
/usr/bin/date +20%y-%m-%d > ~/datsql.txt
If I start it I got this output:

I insert the following line inside my script, but without any... (3 Replies)
Hiya,
Recently I've run a few scripts in the foreground, but have realised later they should of been better nohup'd and placed in the background. I understand how to change a foreground job into a background one, but how would put the job into the nohup state?
Thanks (1 Reply)
on gnome i open a terminal and run wget http://soommmething & in the background. because wget shows me downloading progress percentage and download speed continuously, I exit the gnome-terminal
after a while i want to see the download percentage but dont know how. my ps -u myname shows that... (3 Replies)

Hi all,
I am currently facing a problem when i am submitting a script to run in the background to collect statistics round the clock on an AIX box. I don't have root authority nor can I set it in cron.
So when i submit the job, it runs fine, but won't let me signoff. It prompts me that... (2 Replies)
Hi,
I was running a job in background and because of some immediate work to be done on my machine, I stopped the background job. The real problem comes when I try to restart the same job in the background. To stop I used
stop PID
and to resume the same I use
bg PID
when I do this the... (2 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.
