Simple compress "file.tar" using zlib(gzip) algorithm. Default chunk or per-thread
segment size is 8MB and default compression level is 6.
pcompress -c zlib file.tar
Compress "file.tar" using bzip2 level 6, 64MB chunk size and use 4 threads. In
addition perform identity deduplication and delta compression prior to compression.
pcompress -D -E -c bzip2 -l6 -s64m -t4 file.tar
Compress "file.tar" using zlib and also perform Global Deduplication. Default block
size used for deduplication is 4KB. Also redirect the compressed output to stdout and
send it to a compressed file at a different path.
pcompress -G -c zlib -l9 -s10m file.tar - > /path/to/compress_file.tar.pz
Perform the same as above but this time use a deduplication block size of 8KB.
pcompress -G -c zlib -l9 -B2 -s10m file.tar - > /path/to/compress_file.tar.pz
Compress "file.tar" using extreme compression mode of LZMA and a chunk size of
of 1GB. Allow pcompress to detect the number of CPU cores and use as many threads.
