I' writing a script trying to archive the oldest two directories from one place, tar them, and move them to another.
The problem I'm running into is that the oldest two directories, and some others, were created the same month, date, and different only because their modification time was one or two minutes apart. The oldest two have dates of 2012-07-25, when I run the directory exists check, it will created the directory 2012-07 and move ONE of the two targeted directories into it, the other tar does not go in the target directory but one level up. I want it in /temp/dir/2012-07 one of them goes into that and the other goes to /temp/dir.

After I log ino the machine, a window pops up indicating that I should check that the HOSTNAME is the same in these three files
/etc//rc.configd/netconf

How do I change the hostname in these files?
Thanks,

hi all.
Please help me with archiving previous day syslog files.
the files have no extension and have the format YYYY-MM-DD.
I want to archive the file then move it to some other machine.

Hi there,
I have one huge archive (it's a system image).
I need sometime to create smaller archives with only one or two file from my big archive.
So I'm looking for a command that extracts files from an archive and pipe them to another one.
I tried the following :
tar -xzOf oldarchive.tgz... (5 Replies)

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.
