I don't know what your goal is, but there is a number of gromacs tools
that can do similar things. For example, trjconv can write out every
nth frame into separate files, like this:

trjconv -f traj.xtc -s topol.tpr -o frames.gro -sep -skip 10

will write every 10th frame from traj.xtc into files named 'frames#.gro'
where '#' will be numbers.
