- rooteventselector -f 101 source.root:tree dest.root
  Copy a subset of the tree 'tree' from 'source.root' to 'dest.root'. The new tree contains events from the old tree except the first hundred.
 
- rooteventselector -l 100 source.root:tree dest.root
  Copy a subset of the tree  'tree' from 'source.root' to 'dest.root'. The new tree contains the first hundred events from the old tree.

  Recreate the destination file 'dest.root' and copy the tree 'tree' from 'source.root' to 'dest.root'.
 
- rooteventselector -c 1 source.root:tree dest.root
  Change the compression factor of the destination file 'dest.root' and  copy the tree 'tree' from 'source.root' to 'dest.root'. For more information about compression settings of ROOT file, please look at the reference guide available on the ROOT site.
 
- rooteventselector -s "(branch1Value > 100)&&( branch2Value )" source.root:tree dest.root
  Copy the tree 'tree' from 'source.root' to 'dest.root' and apply a selection to the output tree.
 
- rooteventselector -e "muon_*" source.root:tree dest.root
  Copy the tree 'tree' from 'source.root' to 'dest.root' and remove branches matching "muon_*"
 
- rooteventselector -e "*" -i "muon_*" source.root:tree dest.root
