Tarjei,

not sure, but if you want to make sure that it demuxes, i suggest you look into 
xargs

report_to_generate_ssids_to_be_cloned | xargs -n 1 -I {} -x nsrclone



Kind Regards,
Kris

What will networker do if we pipe the saveset IDs to nsrclone?

e.g. report_to_generate_ssids_to_be_cloned | nsrclone

Is this the same as 1 or 2 above?
