MyPurgeLogs

| Vit | 1.00 |
MyPurgeLogs is a script that can delete files older than a number of days and can rotate and compress other files. It simply reads a configuration file to know what it must do. Wildcards for directories and files are allowed. The compression's method is determined to optimize the free space on the filesystem. This script has only been tested on AIX.

bzip2smp
| Pop | 29.50 |
|---|---|
| Vit | 1.00 |
bzip2smp parallelizes the bzip2 compression process to achieve a near-linear performance increase on SMP machines. On a two-processor Xeon machine, the speedup is around 180%. The tool's main purpose is to aid performing heavy-duty server backups. It can also be used on modern desktop multicore processors (such as AMD Athlon64 X2 and Intel Pentium D).

|---|---|
| Vit | 1.00 |
z3lib is an RFC 1951/1952 compliant compression library with an easy interface. This is a substitute for the well-known zlib compression library.

minihuff
| Pop | 19.49 |
|---|---|
| Vit | 1.00 |
minihuff is a data compression library that enables the creation of a static frequency table to be stored at both ends of a connection. This allows effective compression even for very small pieces of data that maintain similar entropy characteristics.

Tuck
| Pop | 14.80 |
|---|---|
| Vit | 1.00 |
Tuck is a portable, lossless data compression tool based on the Burrows-Wheeler transform, thus ensuring good compression rates. It currently runs quite slowly (slower than the efficient bzip2), mainly because of the block-sorting algorithms involved.

J7Zip
| Pop | 51.96 |
|---|---|
| Vit | 1.00 |
J7Zip handles 7-zip archives. It can lists the contents of the archive, test the archive files, and extract files from the archive to their full paths in the current directory. This version supports only unencrypted archives, and archives with the Copy or LZMA codec.

fuse.gunzip
| Pop | 30.55 |
|---|---|
| Vit | 1.00 |
fuse.gunzip is a filesystem for FUSE that provides transparent decompression of files. The goal is to expedite reading of files by reducing both file size and fragmentation. fuse.gunzip is not a real filesystem such as ext2 or ext3. fuse.gunzip is a virtual proxy filesystem. Compressed files appear as uncompressed when read by the kernel or processes through fuse.gunzip. Any type of file can be compressed.

|---|---|
| Vit | 1.00 |
Maintainer is a collection of scripts that make backup tasks easy and simple. Combined with crontab, Maintainer can be used for automatic backups.

mscompress
| Pop | 32.00 |
|---|---|
| Vit | 1.00 |
The mscompress package contains two programs: msexpand, which decompress files compressed by the Microsoft compress.exe utility (e.g. Win 3.x installation files) and mscompress, which compresses files using the LZ77 compression algorithm. Output files can be decompressed using Microsoft expand.exe or msexpand.

Parallel MPI BZIP2
| Pop | 44.74 |
|---|---|
| Vit | 1.00 |
MPIBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (i.e. anything compressed with MPIBZIP2 can be decompressed with bzip2).
