I dont know if this is what you are looking for but something like this will email it too you daily.
Dont know if this is on the right track, but it is just a simple script that you can put in cron that will check files and email too you. For any other files you want just put them in there as a new line.
Hi Team,
I want to set permissions to one folder in such a way that the user can write files or create folder inside that but should not able to delete it.
Basically reason behind this is i am using Pidgin Messenger. There is a directory of logs in which, when user chat its store his logs.... (2 Replies)
Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin
-r-xr-xr-x 1 bin bin ... (6 Replies)

Hello,
What does the following mean in terms of file permissions.
-rw-rwSrw- 1 owner group 999 May 25 2004 file_name
What does the "S" stand for.
Thanks in advance for your input. :) (3 Replies)
I am starting an audit of unix security within our company and am looking for any information that may assist me with this. I am looking for any tips or pointers that I should be aware of when looking at unix. I am very new to unix so any help will do. Maybe there is someone out the that has had... (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.
