DESCRIPTION
The fpart utility helps you sort file trees and pack them into bags (called "partitions").
GENERAL OPTIONS
-h Print help
-V Print version
PARTITION CONTROL
-n num Create exactly num partitions and try to generate partitions with the same size and
number of files. This option cannot be used in conjunction with -f, -s or -L.
-f files
Create partitions containing at most files files or directories. This option can be
used in conjunction with -s and -L.
-s size
Create partitions with a maximum size of size bytes. With this option, partition 0
may be used to handle files that do not fit in a regular partition, given the
provided size limit. This option can be used in conjunction with -f and -L. You
can use a human-friendly unit suffix here (k, m, g, t, p).
INPUT CONTROL
-i infile
Read file list from infile. If infile is “-”, then list is read from stdin.
-a Input contains arbitrary values; just sort them (do not crawl filesystem). Input
must follow the “size(blank)path” scheme. This option is incompatible with
crawling-related options.
OUTPUT CONTROL
-o outfile
Output partitions' contents to outfile template. Multiple files will be generated
given that template. Each outfile will get partition number as a suffix. If
outfile is “-”, then partitions will be printed to stdout, with partition number
used as a prefix (so you can grep partitions you are interested in, or do whatever
you want).
-0 End filenames with a null (’\0’) character when using option -o.
-e When adding directories (see DIRECTORY HANDLING ), add an ending “/” to each
directory entry.
-v Verbose mode (may be specified more than once).
FILESYSTEM CRAWLING CONTROL
-l Follow symbolic links (default: do not follow).
-b Do not cross filesystem boundaries (default: cross).
-y pattern
Include files or directories matching pattern only (and discard all other files).
This option may be specified several times. Pattern may be a leaf (file or
directory) name or a specific path. Shell pattern matching characters (“[”, “]”,
“*”, “?”) may be used. It does not apply when computing size of directories to be
added once a maximum depth (see option -d ) has been reached (in that case, once the
maximum depth has been reached, every single file accounts for a directory size).
-Y pattern
Same as -y but case insensitive. This option may not be available on your platform
(at least FreeBSD and GNU/Linux support it, Solaris does not).
-x pattern
Exclude files or directories matching pattern. This option can be used in
conjunction with -y and -Y. In this case, exclusion is performed after. This
option may be specified several times. Pattern may be a leaf (file or directory)
name or a specific path. Shell pattern matching characters (“[”, “]”, “*”, “?”) may
be used. It does not apply when computing size of directories to be added once a
maximum depth (see option -d ) has been reached (in that case, once the maximum
depth has been reached, every single file accounts for a directory size).
-X pattern
Same as -x but case insensitive. This option may not be available on your platform
(at least FreeBSD and GNU/Linux support it, Solaris does not).
DIRECTORY HANDLING
-z Pack empty directories. By default, fpart will pack files only (except when using
the -d or -D options). This option can be useful for tools such as rsync(1) to be
able to recreate a full file tree when used with fpart (e.g. using rsync's --files-
from option). See the -zz option to also pack un-readable directories.
-zz Treat un-readable directories as empty, causing them to be packed anyway.
-zzz Pack all directories (as empty). Useful when 3rd party tools need directory entries
to update them (e.g. cpio).
-d depth
After a certain depth, pack directories instead of files (directories themselves
will be added to partitions, instead of their content). You can force a specific
file to be packed anyway by listing it on the command line explicitly.
-D Implies -z. Pack leaf directories: if a directory contains files only, it will be
packed as a single entry. You can force a specific file to be packed anyway by
listing it on the command line explicitly.
-E Implies -D. Pack directories only (work on a per-directory basis): in that mode, no
file will be packed. Instead, each directory will be packed as a single entry with
a size being the sum of all top-level files' sizes. You can force a specific file
to be packed anyway by listing it on the command line explicitly.
LIVE MODE
-L Live mode (default: disabled). When using this mode, partitions will be generated
while crawling filesystem. This option saves time and memory, but does not give
partition 0 a special meaning (see option -s ). As a consequence, it can generate
partitions larger than the size specified with option -s. This option can be used
in conjunction with options -f and -s, but not with option -n.
-w cmd When using live mode, execute cmd when starting a new partition (before having
opened next output file, if any). cmd is run in a specific environment that
provides several variables describing the state of the program: FPART_HOOKTYPE
("pre-part" or "post-part"), FPART_PARTFILENAME (current partition's output file
name), FPART_PARTNUMBER (current partition number), FPART_PARTSIZE (current
partition size), FPART_PARTNUMFILES (number of files in current partition),
FPART_PID (PID of fpart). Note that variables may or may not be defined, depending
of requested options and current partition's state when the hook is triggered.
Also, note that hooks are executed in a synchronous way while crawling filesystem,
so 1) avoid executing commands that take a long time to return as it slows down
filesystem crawling and 2) do not presume cwd (PWD) is the one fpart has been
started in, as it is regularly changed to speed up crawling (use absolute paths
within hooks).
-W cmd Same as -w, but executes cmd when finishing a partition (after having closed last
output file, if any).
SIZE HANDLING
-p num Preload each partition with num bytes. You can use a human-friendly unit suffix
here (k, m, g, t, p).
-q num Overload each file size with num bytes. You can use a human-friendly unit suffix
here (k, m, g, t, p).
-r num Round each file size up to next num bytes multiple. This option can be used in
conjunction with overloading, which is done *before* rounding. You can use a human-
friendly unit suffix here (k, m, g, t, p).
EXAMPLES
Here are some examples:
fpart -n 3 -o var-parts /var
Produce 3 partitions, with (hopefully) the same size and number of files. Three
files: var-parts.0, var-parts.1 and var-parts.2 are generated as output.
fpart -s 4724464025 -o music-parts /path/to/music ./*.mp3
Produce partitions of 4.4 GB, containing music files from /path/to/music as well as
MP3 files from current directory; with such a partition size, each partition content
will be ready to be burnt to a DVD. Files music-parts.0 to music-parts.n, are
generated as output.
find /usr ! -type d | fpart -f 10000 -i - /home | grep '^0:'
Produce partitions containing 10000 files each by examining /usr first and then
/home and display only partition 0 on stdout.
du * | fpart -n 2 -a
Produce two partitions by using du(1) output. Fpart will not examine the file
system but instead use arbitrary values printed by du(1) and sort them.
