Bug

Thanks in2nix4life.

The problem with your script is below piece of code line:

Code:
@UNIQUE = grep(! defined $HASH{$_}, @FILEB);

I thinks the above code matching for entire line. As each line in a.txt varies when compared to b.txt, the given script is simply combining both file contents into output file 'c.txt' as the entire line of a.txt not matches with b.txt.

We need to only match for the first field of b.txt with a.txt. If the first field varies then it has to write inside the output file c.txt.


Code:
input file: a.txt
------------------
x001;frtb70;xyz;109
x001;frvt65;sec;239
m003;wqax34;jul;659
y004;yhud43;yhn;760


input file: b.txt
------------------
x001;abcd80;xyz;193
x001;crrp28;xse;456
p002;lmno10;xyz;784
p002;jfds65;jfd;739
p002;juop88;jup;879
m003;yulo90;rem;542
m003;kihl98;dnt;312
y004;urel25;ewb;342


expected output file: c.txt
---------------------------
x001;frtb70;xyz;109
x001;frvt65;sec;239
p002;lmno10;xyz;784
p002;jfds65;jfd;739
p002;juop88;jup;879
m003;wqax34;jul;659
y004;yhud43;yhn;760

Selecting output lines based on first field of input files are important here and I'm failing there. Any idea will be much useful.

Thanks.

pescetti -- Pseudo-Duplimate Generator SYNOPSIS
pescetti DESCRIPTION
This manual page documents briefly the pescetti command. OPTIONS
Here are a list of the available options and what they do. You must specify exactly one from --demo, --generate or --load. --help Prints the help text --demo Demonstration mode. Generates one hand with permutations and the tutorial for how to use them. --generate=N Generate N random boards --load=boards.txt Load boards+analysis from boards.txt --load-dds=boards.dds Load boards from boards.dds in dds format --load-analysis=tricks.txt Load analysis from tricks.txt --permutations=permutations.txt Generate the permutations and save them to the given file --curtains=curtains.txt Save curtain cards to file curtains.txt --save=boards.txt Save the boards+analysis to boards.txt --save-dds=boards.dds Save the boards to boards.dds in dds format --save-analysis=tricks.txt Save the analysis to tricks.txt --format=html|txt|pdf Set the output mode to the given format --title=title Set the title for the output --output=hands.txt Print the hands to hands.txt, rather than to standard output --stats Generate statistics about the set of boards; included in the hands output --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW) --criteria= A list of criteria to apply to each generated hand to generate specific hand types. The list should be space separated and each item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria. E.g. --criteria="weaknt:0.8 strongnt:0.5" Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441 singlesuit twosuits partscore game slam game-invite slam-invite jumpshift jumpfit splinter bacon weird --probability=factor Generate hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate a board it is rejected if it doesn't match the criteria with the given probability. A factor of about 0.8 gives roughly half matching boards AUTHOR
