MKZFTREE(1)

NAME
mkzftree - Create a zisofs/RockRidge compressed file tree

SYNOPSIS
mkzftree [OPTION]... INPUT OUTPUT

DESCRIPTION

Takes an input file tree (INPUT) and create a corresponding compressed file tree (OUTPUT) that can be used with an appropriately patched mkisofs(8) to create a transparent-compression iso9660/RockRidge filesystem using the "ZF" compression records.

-f  Always compress all files, even if they get larger when compressed.

-zlevel
    Select compression level (1-9, default is 9).

-u  Uncompress an already compressed tree. This can be used to read a compressed filesystem on a system which cannot read them natively.

-pparallelism
    Compress in parallel. The parallelism value indicates how many compression threads are allowed to run.

-x  Do not cross filesystem boundaries.

-v  Increase the program verbosity.

-q  Issue no messages whatsoever, including error messages.

-h  Displays a brief help message.
