OPENSEARCH-DISCOVER(1)					User Contributed Perl Documentation				    OPENSEARCH-DISCOVER(1)

NAME

       opensearch-discover - Find an OpenSearch link from a given URL.

SYNOPSIS

       opensearch-discover [-q] [-v] [-t TITLE] [-1|-a] [-h]  [URL]

DESCRIPTION

       Loads the given URL, searches it for a link to an OpenSearch description URL, and prints that URL.

OPTIONS

       -q, --quiet
	   Give no output on errors. In this case, consult the exit code to determine errors (See "DIAGNOSTICS").

       -v, --verbose
	   Verbose: display titles with links. Combine with -a to see all available searches

       -t TITLE, --title=TITLE
	   Only display links matching TITLE, a case-insensitive perl regular expression. For example, -t book would match Book Search, and -t
	   b.*k would match Book Search or Baby Springbok.

       -1, --first
	   Only display first (matching) link. This is the default.

       -a, --all
	   Display all (matching) links.

       -h, --help
	   Display a short help message.

DIAGNOSTICS

       On success, prints the address of the OpenSearch description file and returns 0.

       If it cannot load the given URL, it returns 1.

       If the given URL does not contain a link to an OpenSearch description file, it returns 2.

       If required perl modules are missing, it returns 3.

DEPENDENCIES

       Requires modules from libwww-perl and HTML::Parser (Debian package libhtml-parser-perl).
