Loop "for" with 2 input

Dear All,
I am stacked in how to do a "for" loop with two input. Well, I try to explain better.

In a folder I have a series of files that are coupled;

Code:
a_1.txt
a_2.txt
b_1.txt
b_2.txt
c_1.txt
c_2.txt

if files were independent a "for" loop should be like that:
Code:
 for file in folder/*.txt
do something $file > ${file%%.*}_executed.txt 
done &
wait

My problem is that my command take two file as input, for instance:

Code:
my_command a_1.txt a_2.txt > output

Well, I would like to do it in a for loop but don't know how.

Any suggestion?




PS: Thanks to MadeInGerman for ${file%%.*}

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
