> ---------------------------------------
>
> Key: NUTCH-1906
> URL: https://issues.apache.org/jira/browse/NUTCH-1906
> Project: Nutch
> Issue Type: Bug
> Components: crawldb
> Affects Versions: 1.9
> Reporter: Lewis John McGibbney
> Assignee: Chris A. Mattmann
> Priority: Trivial
> Fix For: 1.10
>
>
> Currently the CrawlDbReader tool, when invoked without any command line arguments helps us as follows
> {code}
> [mdeploy@crawl local]$ ./bin/nutch readdb
> Usage: CrawlDbReader <crawldb> (-stats | -dump <out_dir> | -topN <nnnn> <out_dir> [<min>] | -url <url>)
> <crawldb> directory name where crawldb is located
> -stats [-sort] print overall statistics to System.out
> [-sort] list status sorted by host
> -dump <out_dir> [-format normal|csv|crawldb] dump the whole db to a text file in <out_dir>
> [-format csv] dump in Csv format
> [-format normal] dump in standard format (default option)
> [-format crawldb] dump as CrawlDB
> [-regex <expr>] filter records with expression
> [-retry <num>] minimum retry count
> [-status <status>] filter records by CrawlDatum status
> -url <url> print information on <url> to System.out
> -topN <nnnn> <out_dir> [<min>] dump top <nnnn> urls sorted by score to <out_dir>
> [<min>] skip records with scores below this value.
> This can significantly improve performance.
> {code}
> The code that bothers me is
> {code}
> -stats [-sort] print overall statistics to System.out
> [-sort] list status sorted by host
> {code}
> The inclusion of the double -sort is not necessary or required.
> Having looked through the code there is no other optional flag which we can substitute for the second one (which I thought may lead to this being a placeholder for something else) therefore we can just remove it.
