Top Forums UNIX for Beginners Questions & Answers Problem with getting awk to multiply a field by a value set based on condition of another field Post 303043838 by cotilloe on Saturday 8th of February 2020 12:18:32 AM

I did not see your reply with the alternate code. Thanks for that. As far as the "algorithm", lol, there really is nothing more to it. The actual file does not contain student grade data but it does have names, categories and title and then a numerical column which needs to be averaged for all titles and then a string value given based on avg per name, as you have helped me with here.

I actually have another issue. Posting it here for reference but will start a new thread and give a bit of back story on it, but I need to do the same EXACT thing, only now in Perl.... Like I said, I will explain more in a new thread, so this one can be closed properly.

Parse::MediaWikiDump::page(3pm) 			User Contributed Perl Documentation			   Parse::MediaWikiDump::page(3pm)

NAME
Parse::MediaWikiDump::page - Object representing a specific revision of a MediaWiki page ABOUT
This object is returned from the "next" method of Parse::MediaWikiDump::Pages and Parse::MediaWikiDump::Revisions. You most likely will not be creating instances of this particular object yourself instead you use this object to access the information about a page in a MediaWiki instance. SYNOPSIS
$pages = Parse::MediaWikiDump::Pages->new('pages-articles.xml'); #get all the records from the dump files, one record at a time while(defined($page = $pages->next)) { print "title '", $page->title, "' id ", $page->id, " "; } STATUS
This software is being RETIRED - MediaWiki::DumpFile is the official successor to Parse::MediaWikiDump and includes a compatibility library called MediaWiki::DumpFile::Compat that is 100% API compatible and is a near perfect standin for this module. It is faster in all instances where it counts and is actively maintained. Any undocumented deviation of MediaWiki::DumpFile::Compat from Parse::MediaWikiDump is considered a bug and will be fixed. METHODS
$page->redirect Returns an empty string (such as '') for the main namespace or a string containing the name of the namespace. $page->categories Returns a reference to an array that contains a list of categories or undef if there are no categories. This method does not understand templates and may not return all the categories the article actually belongs in. $page->title Returns a string of the full article title including the namespace if present $page->namespace Returns a string of the namespace of the article or an empty string if the article is in the default namespace $page->id Returns a number that is the id for the page in the MediaWiki instance $page->revision_id Returns a number that is the revision id for the page in the MediaWiki instance $page->timestamp Returns a string in the following format: 2005-07-09T18:41:10Z $page->username Returns a string of the username responsible for this specific revision of the article or undef if the editor was anonymous $page->userid Returns a number that is the id for the user returned by $page->username or undef if the editor was anonymous $page->userip Returns a string of the IP of the editor if the edit was anonymous or undef otherwise $page->minor Returns 1 if this article was flaged as a minor edit otherwise returns 0 $page->text Returns a reference to a string that contains the article title text perl v5.10.1 2010-12-05 Parse::MediaWikiDump::page(3pm)
