GDBM file dumper

What is GDBM ?

from the man page:

GNU dbm is a library of routines that manages data files that contain key/data pairs. The access provided is that of storing, retrieval, and deletion by key and a non- sorted traversal of all keys. A process is allowed to use multiple data files at the same time.

Dumpgdbm is a batch or interactive tool which can dump keys and data from a GNU DBM file. It can display data in ASCII, decimal, hex, and octal formats. Posix regexp search functions are also provided.

Download the 2002 October edition: dumpgdbm.tar.gz: Read the Makefile first. new in this release: search now use POSIX regex, and CLI use Gnu readline. More fun and more k00L (and may be, more bugs).

Please, send me bugs (or success :) reports.

batch modeinteractive

$ dumpgdbm fichier.gdbm

Important flags:
-x for hexadecimal display, -8 for ascii > 127, -m nnn for the maximum number of displayed bytes.

$ dumpgdbm -i fichier.gdbm

Important commands:
? give you a summary of available commands, and ? xxx give you details on the xxx command.
commands list you commands, with a little explanation.
Look at ks and ds: they take an POSIX regex as argument.
