WebSearch man page

WebSearch — a web-searching application demonstrating WWW::Search


WebSearch [-m MaxCount] [-e SearchEngine] [-o option] [-o option...] [-ardvV] query


This program is provides a command-line interface to web search engines, listing all URLs found for a given query. This program also provides a simple demonstration of the WWW::Search Perl library for web searches.

The program supports a number of search engines; use WebSearch --list to see which backends are installed.

A more sophisticated client is AutoSearch which maintains a change list of found objects.

For examples and hints about searches, see AutoSearch.


WebSearch uses Getopt::Long, so you can use double-minus with long option names, or single-minus with one-letter abbreviations.

--engine e_name, -e e_name
The string e_name is the name of (the module for) the desired search engine. Capitalization matters. See `perldoc WWW::Search` to find out what the default is (probably Null).

Use --list to get a list of installed backends.
--gui, -g
Perform the search to mimic the default browser-based search. Not implemented for all backends, see the documentation for each backend.
Prints to STDERR a \n-separated list of installed backends.
--max max_count, -m max_count
Specify the maximum number of hits to retrieve.
--option o_string, -o o_string
Specify a search-engine option in the form 'key=value' (or just 'key'). Can be repeated for as many options are needed. Keys can be repeated.
--count, -c
As the first line of output, print the approximate hit count. As the last line of output, print the actual hit count.
--terse, -t
Do not print any URLs. Only useful if you also specify --count. If you specify --terse but not --count, there will be no output no matter how many hits are found!
--all, -a
For each hit result, print all the URLs that the search engine indicated were equivalent to it. (Some URLs may refer to the same object.) Can be combined with --verbose; can not be combined with --raw.
--raw, -r
For each hit result, print the raw HTML. Not implemented for all backends.
--verbose, -v
Verbose mode. Enumerate the returned URLs and show the description, score, date, etc. for each.
Print version information and exit immediately.
--debug <i>, -d <i>
Display back-end debugging information (with debug level <i>)
--host <hostname.sub.domain>
Set the _host option for the WWW::Search object (backend-dependent).
--port <i>
Set the _port option for the WWW::Search object (backend-dependent).
--username <bbunny>
Set the username with which to login to the backend.
--password <c4rr0t5>
Set the password with which to login to the backend.
--lwpdebug, -l
Display low-level libwww-perl debugging information
