Top Forums Shell Programming and Scripting Script for identifying and deleting dupes in a line Post 302608282 by ardibehest on Friday 16th of March 2012 07:09:30 PM

Hello,
I wonder if it would be possible to add to Gimley's program. I had written a perl script to identify duplicates in a large file which has a structure similar to Gimley's.
Quote:
word=word1,word2,word3
where Word is the headword and word1, word2, word3 are all equivalents of the word.
It so happens that some times two entries for the same headword can be present.
Quote:
word=word1,word2,word3
word=word1,word4,word5
I have written a program in PERL which identifies such dupes and spews them out in a file where singletons and dupes are clearly identified.
However I have not been able to add to it the added functionality of merging the duplicates into one single entry.
Thus the dupes mentioned above should merge to one single entry:
Quote:
word=word1,word2,word3,word4,word5
Any help given would be greatly appreciated.

Code:
#!/usr/bin/perl

$dupes = $singletons = "";		# This goes at the head of the file

do {
    $dupefound = 0;			# These go at the head of the loop
    $text = $line = $prevline = $name = $prevname = "";
    do {
	$line = <>;
	$line =~ /^(.+)\=.+$/ and $name = $1;
	$prevline =~ /^(.+)\=.+$/ and $prevname = $1;
	if ($name eq $prevname) { $dupefound += 1 }
	$text .= $line;
	$prevline = $line;
    } until ($dupefound > 0 and $text !~ /^(.+?)\=.*?\n(?:\1=.*?\n)+\z/m) or eof;
    if ($text =~ s/(^(.+?)\=.*?\n(?:\2=.*?\n)+)//m) { $dupes .= $1 }
    $singletons .= $text;
} until eof;
print "SINGLETONS\n$singletons\n\DUPES\n$dupes";

Text::FormatTable(3pm)					User Contributed Perl Documentation				    Text::FormatTable(3pm)

NAME
Text::FormatTable - Format text tables SYNOPSIS
my $table = Text::FormatTable->new('r|l'); $table->head('a', 'b'); $table->rule('='); $table->row('c', 'd'); print $table->render(20); DESCRIPTION
Text::FormatTable renders simple tables as text. You pass to the constructor (new) a table format specification similar to LaTeX (e.g. "r|l|5l|R|20L") and you call methods to fill the table data and insert rules. After the data is filled, you call the render method and the table gets formatted as text. Methods: new($format) Create a Text::FormatTable object, the format of each column is specified as a character of the $format string. The following formats are defined: l Left-justified top aligned word-wrapped text. L Left-justified bottom aligned word-wrapped text. r Right-justified top aligned word-wrapped text. R Right-justified bottom aligned word-wrapped text. 10R, 20r, 15L, 12l, Number is fixed width of the column. Justified and aligned word-wrapped text (see above). ' ' A space. | Column separator. head($col1, $col2, ...) Add a header row using $col1, $col2, etc. as cell contents. Note that, at the moment, header rows are treated like normal rows. row($col1, $col2, ...) Add a row with $col1, $col2, etc. as cell contents. rule([$char]) Add an horizontal rule. If $char is specified it will be used as character to draw the rule, otherwise '-' will be used. render([$screen_width]) Return the rendered table formatted with $screen_width or 79 if it is not specified.
