Example

The following sift when added to a command will skip the first 2 elements, then return the distinct remaining elements and then finally count the number of remaining elements that match the regular expression [0-9]: 

    "sift", wasListToCSV([
        "skip", 2,
        "distinct", "",
        "count", "[0-9]"
    ]),

Effect on Returned Data

Given the input 

data=a,1,c,2,c,3,h,2,h,5,j,5

the following transformations will take place:

  1. skip, 2 $\leadsto$ data=c,2,c,3,h,2,h,5,j,5,
  2. distinct $\leadsto$ data=c,2,3,h,5,j,
  3. count, [0-9] $\leadsto$ data=6

and expected output is: 

data=6
