NAME
htdump - write out an ASCII-text version of the document database
SYNOPSIS
htdump [options]
DESCRIPTION
Htdump writes out an ASCII-text version of the document database in the same form as the -t option of htdig.
OPTIONS
-a 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 instead of the default.
-v 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:
u URL
t Title
a State (0 = normal, 1 = not found, 2 = not indexed, 3 = obsolete)
m Last modification time as reported by the server
s Size in bytes
H Excerpt
h Meta description
l Time of last retrieval
L Count of the links in the document (outgoing links)
b Count of the links to the document (incoming links or backlinks)
c HopCount of this document
g Signature of the document used for duplicate-detection
e E-mail address to use for a notification message from htnotify
n Date to send out a notification e-mail message
S Subject for a notification e-mail message
d The text of links pointing to this document. (e.g. <a
href="docURL">description</a>)
A Anchors 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:
i Document ID
l Location of word in document (1 to 1000)
w Weight of word based on scoring factors
c Count of word's appearances in document, if more than 1
a Anchor number if word occurred after a named anchor
FILES
/etc/htdig/htdig.conf
The default configuration file.
/var/lib/htdig/db.docs
The default ASCII document database file.
/var/lib/htdig/db.wordlist
The default ASCII word database file.
