Historically limited, though some versions support redirection
: Users can manually set the number of processors using the -p switch and limit memory usage with the -m switch. Common Commands
Detailed documentation and usage can be found via the Ubuntu Manpages for PBZIP2 . Command Example pbzip2 filename Decompress a file pbzip2 -d filename.bz2 Set specific CPU cores pbzip2 -p4 filename (uses 4 cores) Keep original file pbzip2 -k filename Integrity test pbzip2 -t filename.bz2 Comparison: BZIP2 vs. PBZIP2 Threading Single-threaded Multi-threaded (Parallel) Speed Slower on large files Significantly faster on multi-core systems File Size Standard baseline Slightly larger (~0.2%–0.46%) due to splitting Standard Input Supports stdin/pipes
For further exploration of available versions or similar multi-threaded tools, you can visit SourceForge and search for "pbzip2" or check Linux.com's compression guides .
: Achieves near-linear speedup based on the number of processors.
PBZIP2 is a multi-threaded version of the standard file compressor. It is designed to significantly speed up compression and decompression by utilizing multiple CPU cores simultaneously on SMP machines. Key Technical Features
: Output is fully compatible with bzip2 v1.0.2 or newer, meaning files compressed with PBZIP2 can be opened by standard bzip2 tools.
