NAME

       bup-bloom - generates, regenerates, updates bloom filters

SYNOPSIS

       bup bloom [-d dir] [-o outfile] [-k hashes] [-c idxfile] [-f] [--ruin]

DESCRIPTION

       bup bloom  builds  a  bloom filter file for a bup repository.  If one already exists, it checks the filter and updates or regenerates it as
       needed.

OPTIONS

       --ruin destroy bloom filters by setting the whole bitmask to zeros.  you really want to know what you are doing if run this and you want to
	      delete the resulting bloom when you are done with it.

       -f, --force
	      don't update the existing bloom file; generate a new one from scratch.

       -d, --dir=directory
	      the directory, containing .idx files, to process.  Defaults to $BUP_DIR/objects/pack

       -o, --outfile=outfile
	      the file to write the bloom filter to.  defaults to $dir/bup.bloom

       -k, --hashes=hashes
	      number  of  hash	functions to use only 4 and 5 are valid.  defaults to 5 for repositories < 2 TiB, or 4 otherwise.  See comments in
	      git.py for more on this value.

       -c, --check=idxfile
	      checks the bloom file (counterintuitively outfile) against the specified the .idx.  Does not  write  anything  and  ignores  the	-k
	      option.
