Hi,
How do i remove all the files that are present in the directory.. I know a way of doing this..that is by using *.* .. But my directory has executables or some files without extensions... So they are not getting deleted. What do i do to remove all of them?
Thanks,

I know that rm -i, asks a user before removing a file. What I need to accomplish is removing files from a different directory without switching to that directory. Example: I'm currently in directory dog and I want to remove all the files of a certain name in directory cat, but from within the dog... (5 Replies)

Hi,
I have multiple xml files and named
1233__AAA__12.xml
1234__AAA__12.xml
2125__AAA__13.xml
2127__AAA__13.xml
and I want to delete or to remove only these with the hightest ID e.g. files 1234__AAA__12.xml and 2127__AAA__13.xml.
Could you tell me how can i do that? Is there any script?... (5 Replies)

Howdy.
I'm currently hoping to putty to a number of Linux VMs and update a hosts file remotely before moving on to the next VM in a list. Does anyone have a script that does anything similar? Are there any decent script repositories online? (2 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.
