NAME

estwaver - command line interface of web crawler

SYNOPSIS

estwaver init rootdir

estwaver crawl [-restart|-revisit|-revcont] rootdir

estwaver unittest rootdir

estwaver fetch [-proxy hostr port] [-tout num] [-il lang] url

DESCRIPTION

estwaver is an aggregation of sub commands. The name of a sub command is specified by the first argument. Other arguments are parsed according to each sub command. The argument rootdir specifies the crawler root directory which contains configuration file and so on.

estwaver init rootdir: Create the crawler root directory.
estwaver crawl [-restart|-revisit|-revcont] rootdir: Start crawling.
If -restart is specified, crawling is restarted from the seed documents.
If -revisit is specified, collected documents are revisited.
If -revcont is specified, collected documents are revisited and then crawling is continued.</dd>
estwaver unittest rootdir: Perform unit tests.
estwaver fetch [-proxy hostr port] [-tout num] [-il lang] url: Fetch a document.
url specifies the URL of a document.
-proxy specifies the host name and the port number of the proxy server.
-tout specifies timeout in seconds.
-il specifies the preferred language. By default, it is English.

All sub commands return 0 if the operation is success, else return 1. A running crawler finishes with closing the database when it catches the signal 1 (SIGHUP), 2 (SIGINT), 3 (SIGQUIT), or 15 (SIGTERM).

When crawling finishes, there is a directory _index in the crawler root directory. It is an index available by estcmd and so on.
