Hi dev@, I have been trying to create a webgraph from my crawl data using the documentation here [0]. The command format in the documentation is as follows : >> bin/nutch webgraph (-segment <segment> | -segmentDir <segmentDir> | >> -webgraphdb <webgraphdb>) [-filter -normalize] | -help Upon usage of a command in the above mentioned pattern(-webgraph arg being optional) I got the help message displayed in my shell. I believe that the command should be of the format: >> bin/nutch webgraph (-segment <segment> | -segmentDir <segmentDir> ) >> -webgraphdb <webgraphdb> [-filter -normalize] | -help The above format worked for me. In conclusion -webgraph arg should be mandatory instead of optional. Please feel free to correct me if I am wrong and missing something. Pardon me if I am missing anything silly. Suggestions welcome. Thanks, Omkar. [0] https://wiki.apache.org/nutch/bin/nutch%20webgraph
