Hi! I ran into a problem with a job I'm running. All it is doing is a "touch" on a filename. However, when I ran the job, it error'd out and got the message 'cannot stat'. When I restarted the job (making no changes) it worked just fine. Anyone know what this means? (1 Reply)
From reading various articles on the net, I know stat() is used on files to get things like permissions, sizes etc... As a folder is a special type of file in Unix, I assumed that stat() could work on it as well as any general file.
However, from running my program, perror() reported that the... (3 Replies)
If i do ls -l i get the result rwx-rw-r ...... ............... file.
How can i get the result in octal format.
All other output will be the same as ls -l shows.
The rwx-rw-r would be like 755 etc. (7 Replies)
i know this command does not exist in solaris. however, i read somewhere on this forum that basically everything the stat command provides in other oses can be obtained in solaris using the ls command.
i've searched the forum for a while now and i cant find the thread. does anyone know about... (1 Reply)
Die to what all operations, the "Modify" and "Change" values of stat output changes for a file.
I found, during editing a file, Change and Modify alters. When chmod'ing Change alters, while Modify doesnot alters. Is there more situations where these changes? (1 Reply)
Hi Experts,
I am here with very simple request:

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.
