For Loop to execute a command on a series of files
Hello,

I have a set of input data that I split into batches using the following command:

split -l 4000000 MyInput.in Split_a

Once I get the split files, I run a certain command on the split files that spews an output. So far I have been doing it without a for loop. How can I translate the following pseduo code so that I don't need to execute the command for every single split input.

For all the files that have been split
do
command <Split_a*.in> <Split_a*.out>
done

Thanks,
Gussi
