How To Install bitshuffle on Kali Linux
Introduction
In this tutorial we learn how to install bitshuffle on Kali Linux.
What is bitshuffle
Bitshuffle is an algorithm that rearranges typed, binary data for improving compression, as well as a python/C package that implements this algorithm within the Numpy framework.
The library can be used along side HDF5 to compress and decompress datasets and is integrated through the dynamically loaded filters framework. Bitshuffle is HDF5 filter number 32008.
Algorithmically, Bitshuffle is closely related to HDF5’s Shuffle filter except it operates at the bit level instead of the byte level. Arranging a typed data array in to a matrix with the elements as the rows and the bits within the elements as the columns, Bitshuffle “transposes” the matrix, such that all the least-significant-bits are in a row, etc. This transpose is performed within blocks of data roughly 8kB long.
This does not in itself compress data, only rearranges it for more efficient compression. To perform the actual compression you will need a compression library. Bitshuffle has been designed to be well matched Marc Lehmann’s LZF as well as LZ4. Note that because Bitshuffle modifies the data at the bit level, sophisticated entropy reducing compression libraries such as GZIP and BZIP are unlikely to achieve significantly better compression than simpler and faster duplicate-string-elimination algorithms such as LZF and LZ4. Bitshuffle thus includes routines (and HDF5 filter options) to apply LZ4 compression to each block after shuffling.
The Bitshuffle algorithm relies on neighbouring elements of a dataset being highly correlated to improve data compression. Any correlations that span at least 24 elements of the dataset may be exploited to improve compression.
There are three ways to install bitshuffle on Kali Linux . We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install bitshuffle Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install bitshuffle using apt-get by running the following command:
sudo apt-get -y install bitshuffle
Install bitshuffle Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install bitshuffle using apt by running the following command:
sudo apt -y install bitshuffle
Install bitshuffle Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install bitshuffle using aptitude by running the following command:
sudo aptitude -y install bitshuffle
How To Uninstall bitshuffle on Kali Linux
To uninstall only the bitshuffle package we can use the following command:
sudo apt-get remove bitshuffle
Uninstall bitshuffle And Its Dependencies
To uninstall bitshuffle and its dependencies that are no longer needed by Kali Linux, we can use the command below:
sudo apt-get -y autoremove bitshuffle
Remove bitshuffle Configurations and Data
To remove bitshuffle configuration and data from Kali Linux we can use the following command:
sudo apt-get -y purge bitshuffle
Remove bitshuffle configuration, data, and all of its dependencies
We can use the following command to remove bitshuffle configurations, data and all of its dependencies, we can use the following command:
sudo apt-get -y autoremove --purge bitshuffle
