WebSearch - a web-searching application demonstrating WWW::Search
WebSearch [-m MaxCount] [-e SearchEngine] [-o option] [-o option...] [-ardvV]
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
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
- Prints to STDERR a \n-separated list of installed
- --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
- --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, -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.
- --VERSION, -V
- Print version information and exit immediately.
- --debug <i>, -d <i>
- Display back-end debugging information (with debug level
- --host <hostname.sub.domain>
- Set the _host option for the WWW::Search object
- --port <i>
- Set the _port option for the WWW::Search object
- --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
The environment variable http_proxy
) specifies a
proxy, if any.
