htdump [options]


Htdump writes out an ASCII-text version of the document database in the same form as the -t option of htdig.


Use alternate work files. Tells htdump to append .work to database files, allowing it to operate on a second set of databases.
-c configfile
Use the specified configfile file instead of the default.
Verbose mode. This doesn't have much effect.

File Formats

Document Database

Each line in the file starts with the document id followed by a list of fieldname:value separated by tabs. The fields always appear in the order listed below:

fieldname value
aState (0 = normal, 1 = not found, 2 = not indexed, 3 = obsolete)
mLast modification time as reported by the server
sSize in bytes
hMeta description
lTime of last retrieval
LCount of the links in the document (outgoing links)
bCount of the links to the document (incoming links or backlinks)
cHopCount of this document
gSignature of the document used for duplicate-detection
eE-mail address to use for a notification message from htnotify
nDate to send out a notification e-mail message
SSubject for a notification e-mail message
dThe text of links pointing to this document. (e.g. <a href="docURL">description</a>)
AAnchors in the document (i.e. <A NAME=...)

Word Database

While htdump and htload don't deal with the word database directly, it's worth mentioning it here because you need to deal with it when copying the ASCII databases from one system to another. The initial word database produced by htdig is already in ASCII format, and a binary version of it is produced by htmerge, for use by htsearch. So, when you copy over the ASCII version of the document database produced by htdump, you need to copy over the wordlist as well, then run htload to make the binary document database on the target system, followed by running htmerge to make the word index.

Each line in the word list file starts with the word followed by a list of fieldname:value separated by tabs. The fields always appear in the order listed below, with the last two being optional:

fieldname value
iDocument ID
lLocation of word in document (1 to 1000)
wWeight of word based on scoring factors
cCount of word's appearances in document, if more than 1
aAnchor number if word occurred after a named anchor


The default configuration file.
The default ASCII document database file.
The default ASCII word database file.
