Splitting command line args with GNU parallel

Question

Using GNU parallel: http://www.gnu.org/software/parallel/

I have a program that takes two arguments, e.g.

$ ./prog file1 file2
$ ./prog file         


        

Answer 1

You are probably looking for --colsep.

generate_file_pairs | parallel --colsep ' ' ./prog {1} {2}  

Read man parallel for more. And watch the intro video if you have not already done so http://www.youtube.com/watch?v=OpaiGYxkSuQ
