Script for identifying and deleting dupes in a line
I am compiling a synonym dictionary which has the following structure
Headword=Synonym1,Synonym2 and so on, with each synonym separated by a comma.
As is usual in such cases manual preparation of synonyms results in repeating the synonym which results in dupes as in the example below:
Code:
arrogance=affectation,affected manners,airs,array,boastfulness,boasting,bombast,braggadocio,bravado,brazenness,bumptiousness,conceit,contempt,contemptuousness,contumeliousness,contumely,coxcombry,crowing,dandyism,dash,disdain,disdainfulness,display,egotism,fanfare,fanfaronade,fatuousness,flourish,foppery,foppishness,frills and furbelows,frippery,gall,getting on one's high horse,glitter,gloating,haughtiness,hauteur,high notions,highfalutin' ways,loftiness,nerve,ostentation,overconfidence,pageantry,panache,parade,pomp,pomposity,pompousness,presumption,presumptuousness,pretension,pretentiousness,pride,putting on the dog,putting one's nose in the air,scorn,scornfulness,self-importance,shamelessness,show,showiness,affected manners,airs,array,snobbery,snobbishness,superciliousness,swagger,vainglory,vanity,affected manners

As can be seen
affected manners
is repeated and so are quite a few other synonyms.
I had written a script which basically does the following:
places each synonym on a line by replacing the comma by a CR/LF
sorting the synonym set
replacing the sorted unique synonyms in the structure Headword=syn1,syn2 etc.
Although it works, it is expensive and time consuming considering that the number of synonym sets is around 100,00
A perl or awk script which does the job faster would be really appreciated. Please note that a given headword can admit upto 100 synonyms, each separated by a comma.
Many thanks for a faster solution.

htfuzzy

htdig(1)						      General Commands Manual							  htdig(1)

NAME

       htfuzzy - fuzzy command-line search utility for the ht://Dig search engine

SYNOPSIS

       htfuzzy [-c configfile] [-v] algorithm [options]

DESCRIPTION

       Description to follow here

OPTIONS

       -c configfile
	      Use the specified configfile instead of the default.

       -v     Verbose mode Use this to get more verbose output while running htfuzzy. More than one v can be specified (ie.  -vv , -vvv
	       etc ). Specifying more than two v's is probably only useful for debugging purposes.

Supported Algorithms
       Different algorithms are supported for searching:
	      soundex  Creates	 a  slightly modified soundex key database. Differences with the standard soundex algorithm are: Keys are 6 digits
	      and the first letter is also encoded.	   metaphone Creates a metaphone key database. This algorithm is more specific to English,
	      but  will  get  fewer  "weird" matches than the soundex algorithm.

	      accents (No description of the algorithm at the moment)

	      endings Creates  two  databases  which  can  be  used  to match common word endings. The creation of these databases requires a list
	      of affix rules and a dictionary which uses those affix rules. The format of the affix  rules and	dictionary   files  are  the  ones
	      used  by	the  ispell program. Included with the distribution are the affix rules for English and a fairly small English dictionary.
	      Other languages can be supported	by  getting  the appropriate affix rules and dictionaries. These are available for many languages;
	      check the ispell distribution for more details.

	      synonyms	Creates a database of synonyms for words. It reads a text database of synonyms and creates a  database	that htsearch  can
	      then use. Each line of the text database consists of words where the first word will have the other words on that line as synonyms.

Notes on searching
       Please consult specialised literature to find out how the different algorithms work or simply try another
	      search strategy you do not get the intended search results.

FILES

       /etc/htdig/htdig.conf
	      The default configuration file.

SEE ALSO

       Please refer to the HTML pages (in the htdig-doc package) /usr/share/doc/htdig-doc/html/index.html and the manual  pages  htdigconfig(8)  ,
       htmerge(1) , htnotify(1) , htsearch(1) and rundig(1) for a detailed description of ht://Dig and its commands.

AUTHOR

       This  manual  page  was	written by Robert Ribnitz. It is based on documentation of ht://Dig, and on earlier manpages provided by Christian
       Schwarz and Stijn de Bekker.
