db allows manipulation of
  btree(3) and
  hash(3)
  (db(3)) databases.
db has three modes of operation to perform
    upon dbfile:
-d. Deletes the given
      keys, and keys described in
      infile.-w. Writes the given
      keys and values, and keys and
      values described in infile (in the latter case,
      entries are separated by insep).There are two mandatory arguments: type is the database type; either ‘btree’ or ‘hash’, and dbfile is the database file to manipulate.
Options valid for all modes are:
-E
    endian-f
    infilestdin is
      used.-i-NBy convention, each key and value in the underlying database
        is terminated with a NUL byte, although it is possible to have keys or
        values that are not so terminated. Without the
        -N option, db adds a NUL
        terminator to any keys and values specified on the command line or in
        the input file, before searching or modifying the underlying database,
        and removes the last byte (which is usually a NUL terminator) before
        printing any keys and values retrieved from the underlying database.
        With the -N option, db
        does not add or remove a terminating byte. The
        -S, -T, and
        -U options may be useful to encode the NUL
        terminator in a readable form.
-q-d) and write
      (-w) modes, the result of various operations is
      suppressed.-T
    visspec-S option
      are encoded and -U option are decoded. The
      visspec option-argument is a string specifying
      strsvisx(3) flags. The
      string consists of one or more characters:
    VIS_NOSLASHVIS_CSTYLE.
          Overrides h and o.VIS_HTTPSTYLE.
          Overrides c and o.VIS_OCTAL.
          Overrides c and h.VIS_SAFEVIS_TABVIS_WHITE-U only supports
        -T h.
See vis(1)'s corresponding options for the meaning of these characters, and strsvisx(3) for more detail on the flags.
-U

-D-K-O
    outsep-S
    visitem-V-X
    extravis-S option also encode
      characters in extravis, per
      strsvisx(3).-K or
  -V is given, both options are enabled.)Write mode specific options are:
-C-D-R to be useful.)-F
