UNIX loop question

Dear all,

I have a question regarding unix loops. I want to run 100 commands using file1.txt-file100.txt in parallel. I use the code below and it works well. But now I want to run first 20 commands first using file1.txt-file20.txt in parallel, then when they are completed, run the next 20 commands in parallel, then the next 20 commands ... and so on. But I don't know how to modify the code to do that. Does anyone know how to write the code? Thank you for your time and help in advance.

Code:
for snplist in $(seq 1 100); do plink --bfile mydata  --extract file${snplist}.txt --make-bed --out file${snplist}& done

thanks,
Lin
