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%%.*}

NAME
POE::Test::Loops - Reusable tests for POE::Loop authors SYNOPSIS
#!/usr/bin/perl -w use strict; use Getopt::Long; use POE::Test::Loops; my ($dir_base, $flag_help, @loop_modules, $flag_verbose); my $result = GetOptions( 'dirbase=s' => $dir_base, 'loop=s' => @loop_modules, 'verbose' => $flag_verbose, 'help' => $flag_help, ); if ( !$result or !$dir_base or $flag_help or !@loop_modules ) { die( "$0 usage: ", " --dirbase DIR (required) base directory for tests ", " --loop MODULE (required) loop modules to test ", " --verbose show some extra output ", " --help you're reading it ", ); } POE::Test::Loops::generate($dir_base, @loop_modules, $flag_verbose); exit 0; DESCRIPTION
POE::Test::Loops contains one function, generate(), which will generate all the loop tests for one or more POE::Loop subclasses. The "SYNOPSIS" example is a version of poe-gen-tests, which is a stand-alone utility to generate the actual tests. poe-gen-tests also documents the POE::Test::Loops system in more detail. FUNCTIONS
generate( $DIRBASE, @LOOPS, $VERBOSE ) Generates the loop tests. DIRBASE is the (relative) directory in which a subdirectory for each of the LOOPS is created. If VERBOSE is set to a TRUE value some progress reporting is printed. POE::Test::Loops::generate( "./t", [ "POE::Loop::Yours" ], 1, ); SEE ALSO
