Hi All,
I have a situation where I need to copy the files having the latest date.
For example I have a file by name bas100e1_jun05. I need to copy it to bas100e1. But when a file by name bas100e1_jul05 is put in the same directory the script should copy the file having the latest month which... (34 Replies)
1) How do I get the name of latest file in a variable?
2) Is it safe to delete all files from a dir
I am doing
cd $dir_name
if return_code > 0
rm *
fi
what are other alternates to delete all files from a dir in a shell script?

Hello
I have three directory structures for code releases.
Each directory structure looks like this:
bash-3.00$ ls -R | more
.:

Test_Release_2
Test_Release_3
./Test_Release_1/dbcode:

ls -lrt | nawk -v D="$(date +'%b%e:'| sed 's/ //g')" 'D==$6$7":"{sub(".*"$9,$9);print}'
This picks only the latest files created based on the timestamp for that particular day..
how do i copy over the same files to a different location???? (1 Reply)

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.
