NoSQL operator: total
Sums up selected table columns.
Usage: total [options] [column ...]
Options:
--input (-i) 'file'
Read input from 'file' instead of STDIN.
--output (-o) 'file'
Write output to 'file' instead of STDOUT.
--help (-h)
Display this help text.
--no-header (-N)
Suppress table header from output.
--total (-T) 'column'
The table will be appended an extra column with the
specified 'column' name, containing the grand-total
of the columns that were summed.
--report (-r)
Print the whole table to STDOUT, along with totals.
--last (-l)
If the input table contains duplicated column names
pick the last occurrence of each. The default is to
pick the first one. This is sometimes useful after
the 'jointable' operator.
Notes:
Adds the values in the selected columns and displays them.
If no columns are specified, then nothing is summed.
