Bup 0.33.7                                         2025-01-11                                       bup-bloom(1)

       Part of the bup(1) suite.

       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.

       bup-bloom - generates, regenerates, updates bloom filters

       --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 .idx file, first checks
              that the bloom filter is claiming to contain the .idx, then checks that it does  actually  contain
              all of the objects in the .idx.  Does not write anything and ignores the -k option.
