/usr/bin/pixz: invalid option -- '-'
pixz: Parallel Indexing XZ compression, fully compatible with XZ
Basic usage:
pixz input output.pxz # Compress a file in parallel
pixz -d input.pxz output # Decompress
Tarballs:
pixz input.tar output.tpxz # Compress and index a tarball
pixz -d input.tpxz output.tar # Decompress
pixz -l input.tpxz # List tarball contents very fast
pixz -x path/to/file < input.tpxz | tar x # Extract one file very fast
tar -Ipixz -cf output.tpxz dir # Make tar use pixz automatically
Input and output:
pixz < input > output.pxz # Same as `pixz input output.pxz`
pixz -i input -o output.pxz # Ditto
pixz [-d] input # Automatically choose output filename
Other flags:
-0, -1 ... -9 Set compression level, from fastest to strongest
-p NUM Use a maximum of NUM CPU-intensive threads
-t Don't assume input is in tar format
-k Keep original input (do not remove it)
-c ignored
-h Print this help

|---|
-0, -1 ... | Set compression level, from fastest to strongest | help |
-p NUM | Use a maximum of NUM CPU-intensive threads | help + man |
-t | Don't assume input is in tar format | help + man |
-k | Keep original input (do not remove it) | help |
-c | ignored | help |
-h | Show pixz’s online help. | help + man |
-d | Decompress, instead of compress. (in the manual page but not in --help) | man |
-l | List the archive contents. (in the manual page but not in --help) | man |
-x PATH | Extract certain members from an archive, quickly. (in the manual page but not in --help) | man |
-i INPUT | Use INPUT as the input. (in the manual page but not in --help) | man |
-o OUTPUT | Use OUTPUT as the output. (in the manual page but not in --help) | man |
-# | Set compression level, from -0 (lowest compression, fastest) to -9 (highest compression, slowest). (in the manual page but not in --help) | man |
-e | Use "extreme" compression, which is much slower and only yields a marginal decrease in size. (in the manual page but not in --help) | man |
-f FRACTION | Set the size of each compression block, relative to the LZMA dictionary size (default is 2.0). (in the manual page but not in --help) | man |
-q SIZE | Set the number of blocks to allocate for the compression queue (default is 1.3 cores + 2, rounded up). (in the manual page but not in --help) | man |
