MKZFTREE(1)

NAME
mkzftree - Create a zisofs/RockRidge compressed file tree

SYNOPSIS
mkzftree [OPTIONS]... 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, --force
    Always compress all files, even if they get larger when compressed.

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

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

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

-x, --one-filesystem
    Do not cross filesystem boundaries, but create directory stubs at mount points.

-X, --strict-one-filesystem
    Do not cross filesystem boundaries, and do not create directory stubs at mount points.

-l, --local
    Do not recurse into subdirectories, but create the directories themselves.

-L, --strict-local
    Do not recurse into subdirectories, and do not create directories.

-F, --file
    Indicates that INPUT may not necessarily be a directory; this allows operation on a single file. Note especially that if -F is specified, and INPUT is a symlink, the symlink itself will be copied rather than whatever it happens to point to.

-s, --sloppy
    Treat file modes, times and ownership data as less than precious information and don't abort if they cannot be set.

-v, --verbose
    Increase the program verbosity.

-V value, --verbosity value
    Set the program verbosity to value.

-q, --quiet
    Issue no messages whatsoever, including error messages. This is the same as specifying -V 0.

-h, --help
    Display a brief help message.

-w, --version
    Display the release version.

BUGS
Long options (beginning with --) may not work on all systems. See the message printed out by mkzftree -h to see if this applies to your system.

Inode change times (ctimes) are not copied. This is a system limitation and applies to all file copy programs.

If using the parallel option (-z) the access times (atimes) on directories may or may not be copied. If it is important that the atimes on directories are copied exactly, avoid using -z.
