mkzftree - Create a zisofs/RockRidge compressed file tree
mkzftree [OPTIONS]... INPUT OUTPUT
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 ISO 9660/Rock Ridge
filesystem using the "ZF" compression records.
Always compress all files, even if they get larger when
-z level, --level level
Select compression level (1-9, default is 9). Lower compression
levels are faster, but typically result in larger output.
Uncompress an already compressed tree. This can be used to read
a compressed filesystem on a system which cannot read them
-p parallelism, --parallelism parallelism
Compress in parallel. The parallelism value indicates how many
compression threads are allowed to run.
Do not cross filesystem boundaries, but create directory stubs
at mount points.
Do not cross filesystem boundaries, and do not create directory
stubs at mount points.
-C path, --crib-tree path
Steal ("crib") files from another directory if it looks (based
on name, size, type and modification time) like they match
entries in the new filesystem. The "crib tree" is usually the
compressed version of an older version of the same workload;
this thus allows for "incremental rebuilds" of a compressed
filesystem tree. The files are hardlinked from the crib tree to
the output tree, so if it is desirable to keep the link count
correct the crib path should be deleted before running mkisofs.
The crib tree must be on the same filesystem as the output tree.
Do not recurse into subdirectories, but create the directories
Do not recurse into subdirectories, and do not create
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.
Treat file modes, times and ownership data as less than precious
information and don’t abort if they cannot be set. This may be
useful if running mkisofs on an input tree you do not own.
Increase the program verbosity.
-V value, --verbosity value
Set the program verbosity to value.
Issue no messages whatsoever, including error messages. This is
the same as specifying -V 0.
Display a brief help message.
Display the release version.
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
Inode change times (ctimes) are not copied. This is a system
limitation and applies to all file copy programs.
If using the parallel option (-p) 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 -p.
