NAME

       gaffitter - File subsets extractor based on genetic algorithms

SYNOPSIS

       gaffitter -t|--target value[unit] [OPTION]... FILE...
       gaffitter - -t|--target value[unit] [OPTION]... [FILE]...

DESCRIPTION

       gaffitter  (Genetic  Algorithm File Fitter) is a command-line software written in C++ that
       extracts --via genetic algorithm-- subsets of an input list of files/directories that best
       fit the given volume size (target), such as CD, DVD and others.

       If gaffitter is executed using the second option listed above, the information about files
       is fetched from stdin.

       The unit suffixes 'k', 'm', 'g' or 't' can be used, where: k = KB/KiB, m  =  MB/MiB,  g  =
       GB/GiB and t = TB/TiB. Default: bytes.

OPTIONS

       General options:

       -t, --target VALUE[unit] (float)
              Set VALUE as target size (mandatory), VALUE > 0.0

       --bins, --vols VALUE[unit]
              Set VALUE as the maximum number of bins (volumes). [default = "unlimited"]

       --si   Use powers of 1000 (not 1024) for target, min, max and output sizes.

       --min, --min-size VALUE[unit]
              Minimum file size. [default = none]

       --max, --max-size VALUE[unit]
              Maximum file size. [default = none]

       -B, --block-size VALUE
              The smallest amount of bytes a file can occupy. [default = 1]

       --ss, --show-size
              Print the size of each file.

       --sb, --show-bytes
              Also print the sizes in bytes.

       --hi, --hide-items
              Don't print selected files.

       --hs, --hide-summary
              Hide summary line containing sum, difference and number of selected files.

       -s, --sort-by-size
              Sort the output by size, not by name.

       -n, --no-case
              Use case-insensitive sorting.

       -r, --sort-reverse
              Sort the output in reverse order.

       --ew, --enclose-with CHAR
              Enclose file names with CHAR. [default = none]

       --dw, --delimit-with CHAR
              Delimit file names (lines) with CHAR. [default = newline]

       -z, --null-data
              Assume NULL ( ) as the delimiter of input files via stdin (pipe).

       -Z, --null
              Same as --dw '\0'. See also the -0 and --hs options.

       -0, --null-bins
              Same as --bs '\0'. See also the -Z and --hs options.

       --bs, --bins-separator CHAR
              Separate bins (vols) with CHAR. [default = newline]

       --version
              Print gaffitter version and exit.

       -v, --verbose
              Verbose.

       -h, --help
              Print help and exit.

       Direct Input options:

       --di, --direct-input
              Switch to direct input mode, i.e., read directly "size identifier" pairs instead of
              file names.

       --di-b, --di-bytes
              Assume input sizes as bytes.

       --di-k, --di-kb
              Assume input sizes as kibi bytes (KiB). KB if --di-si.

       --di-m, --di-mb
              Assume input sizes as mebi bytes (MiB). MB if --di-si.

       --di-g, --di-gb
              Assume input sizes as gibi bytes (GiB). GB if --di-si.

       --di-t, --di-tb
              Assume input sizes as tebi bytes (TiB). TB if --di-si.

       --di-si
              Use powers of 1000 (not 1024) for input sizes.

       Genetic Algorithm options:

       --ga-s, --ga-seed VALUE (integer)
              GA initialization seed, VALUE >= 0. Zero means random. [default = 1]

       --ga-rs, --ga-random-seed
              Use rendom GA seed (same as --ga-seed 0).

       --ga-ng, --ga-num-generations VALUE (integer)
              Maximum number of generations, VALUE > 0. [default = auto]

       --ga-ps, --ga-pop-size VALUE (integer)
              Number of individuals, VALUE > tournament_size. [default = auto]

       --ga-cp, --ga-cross-prob VALUE (float)
              Crossover probability, 0.0 <= VALUE <= 1.0. [default = 0.95]

       --ga-mp, --ga-mutation-prob VALUE (float)
              Mutation probability (per gene), 0.0 <= VALUE <= 1.0. [default = auto]

       --ga-sp, --ga-sel-pressure VALUE (integer)
              Selection pressure (tournament size), 2 <= VALUE < pop_size. [default = 2]

       --ga-theo, --ga-theoretical [VALUE] (integer)
              Stop if the theoretical minimum number of bins is reached. If VALUE is given, it is
              assumed to be the theoretical minimum number of bins.

       Other search methods:

       --ap, --approximate
              Approximate the solution using Best First search (non-optimal but very fast).

       --sp, --split
              Just  split  the  input when target size is reached (preserves original order while
              splitting).
