#doodled(1) - Linux man page
Name
doodled - a daemon to keep your doodle database up-to-date
Synopsis
doodled [OPTIONS] [FILENAMES]*
Description
doodled monitors your filesystem for changes and updates the doodle database to keep it always up-to-date with the latest data. doodled is experimental at this point. It uses libfam and is thus limited to monitoring less than 1024 directories for changes.

Options

-d FILENAME, --database=FILENAME
use FILENAME for the location of the database (use when building or searching). This option is particularly useful when doodle is used to search different types of files (or is operated with different extractor options). Using this option doodle can be used to build specialized indices (i.e. one per file system), which can in turn improve search performance. When searching, you can pass a colon-separated list of database file names, in that case all databases are searched. Note that the disk-space consumption of a single database is typically slightly smaller than if the database is split into multiple files. Nevertheless, the space-savings are likely to be small (a few percent). You can also use the environment variable DOODLE_PATH to set the list of database files to search. The option overrides the environment variable if both are used. If the option is not given and DOODLE_PATH is not set, "/.doodle" is used.
-D, --debug
do not detach from the terminal (do not daemonize). Also will print log messages to stderr if no logfile is specified.
-f, --filenames
include filenames (full path) in the set of keywords
-h, --help
print help page
-l LIBRARIES, --library=LIBRARIES
specify which libextractor plugins to use (for building the index with -b or for printing information about files with -e)
-L FILENAME, --log=FILENAME
log messages to the given logfile.
-m LIMIT, --memory=LIMIT
use at most LIMIT MB of memory for the nodes of the suffix-tree (after that, serialize to disk). Note that a smaller value will reduce memory consumption but increase the size of the temporary file (and slow down indexing). The default is 8 MB.
-n, --nodefault
do not load the default set of plugins (only load plugins specified with -l)
-P PATH, --prunepaths=PATH
Directories to not put in the database, which would otherwise be. The environment variable PRUNEPATHS also sets this value. Default is "/tmp /usr/tmp /var/tmp /dev /proc /sys". This option can also be used when searching, in which case search results in the specified directories will be ignored.
-v, --version
print the version number
-V, --verbose
be verbose
Environment
DOODLE_PATH
Colon-separated list of databases to search. Note that when building the database this path must either only contain one filename or the option -b must be used to specify the database file. Default is "/.doodle".
PRUNEPATHS
Space-separated list of paths to exclude. Can be overridden with the -P option.

#Notes
Doodle depends on GNU libextractor.

• GNU Libextractor
  libextractor
  GNU Libextractor is a library used to extract meta data from files. The goal is to provide developers of file-sharing networks, browsers or WWW-indexing bots with a universal library to obtain simple keywords and meta data to match against queries and to show to users instead of only relying on filenames. libextractor contains the shell command extract that, similar to the well-known file command, can extract meta data from a file and print the results to stdout.

Currently, libextractor supports the following formats: HTML, MAN, PS, DVI, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), FLAC, MP3 (ID3v1 and ID3v2), OGG, WAV, S3M (Scream Tracker 3), XM (eXtended Module), IT (Impulse Tracker), NSF(E) (NES music), SID (C64 music), EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), LZH, LHA, RAR, ZIP, CAB, 7-ZIP, AR, MTREE, PAX, CPIO, ISO9660, SHAR, RAW, XAR FLV, REAL, RIFF (AVI), MPEG, QT and ASF. Also, various additional MIME types are detected.

GNU libextractor uses helper-libraries (plugins) to perform the actual extraction. As a result, GNU libextractor can be extended simply by installing additional plugins. Writing robust parsers can be difficult. GNU libextractor protects the main applications from haning or crashing plugins by executing all plugins out-of-process.
