DESCRIPTION

13       pxz  is  a  compression utility that takes advantage of running XZ com‐
14       pression simultaneously on different parts of an input file on multiple
15       cores and processors. This significantly speeds up compression time.

EXAMPLES

43       pxz file1 file2
44              Compress file1 and file2 to file1.xz and file2.xz using  default
45              settings.
46
47       pxz -T4 file1
48              Compress  file1  with  default  compression  and  maximum  of  4
49              threads.
50
51       pxz -k -9 file1
52              Use maximal compression and keep the original file1, use default
53              number of threads.
54
55       pxz -f -T4 file1
56              Compress file with default compression and with 4 threads.
57
58       pxz -kvf -3 -T8 file1
59              Use  -3  compression,  keep the original file, use 8 threads and
60              show progress.
61
62       tar Oc dir1 | pxz -D 12 -cv - > dir1.tar.xz
63              Move dir1 into tar, then compress it  with  the  context  of  12
64              sizes  of  dictionary per thread, show progress and write result
65              to dir1.tar.xz.
