SYNOPSIS
mkzftree [OPTIONS]... INPUT OUTPUT
DESCRIPTION
Takes an input file tree (INPUT) and create a correspond
ing 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 indi
cates 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 cre
ate 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 cre
ate 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
Display a brief help message.
-w, --version
Display the release version.
BUGS
Long options (beginning with --) may not work on all sys
tems. 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.
