                      NoSQL operator: subtotal

Compute subtotals on selected table columns.

Usage:  subtotal [options] B_column ... -s column ...

Options:
    --help (-h)
      Print this help info.

    --total (-t)
      Include totals.

    --total-only (-T)
      Total Only Option. Just do totals on specified columns. In this
      case the '-s' flag is not necessary.

Notes:

Lists subtotals of specified subtotal column(s) (those following the '-s'
flag) whenever the value of break columns(s) (B_column) changes.

If no break column(s) are given the first column is used; if no sub-total
columns are given then all columns of type numeric are sub-totaled.

This operator reads an rdbtable via STDIN and writes an rdbtable via STDOUT.
Options may be abbreviated.
