gdbmtool 1.14.1-3 (i386 binary) in ubuntu bionic

 GNU dbm ('gdbm') is a library of database functions that use extendible
 hashing and works similarly to the standard UNIX 'dbm' functions. This
 package includes following command line tools:
 .
  * gdbm_dump -- dump database content into system-independant format
  * gdbm_load -- recreate database from dump, created by gdbm_dump
  * gdbmtool -- view and modify an existing database or to create a new one.
