Overview ¶
Total totals columns of its input.
Usage:
total [-F regexp | -csv] [file...]
Total sums the values in the named files (or else standard input). Each file is read as a sequence of records, one per line. Each line is read as a list of space-separated fields in the manner of Go's strings.Fields. Total prints the sum of all the corresponding fields in the records: the total of all the first fields, the total of all the second fields, and so on.
If a given field in any record is non-numeric, meaning it cannot be parsed by Go's strconv.ParseFloat, then the sum for that field is printed as "~". As a special case, if all records contain the same non-numeric string for a given field, then the sum for that field is that string.
The -F flag specifies a Go regular expression to use as an input field separator instead of using strings.Fields. It does not affect the output, which is printed with single spaces between all fields.
The -csv flag specifies that the input lines should be treated as CSV data and that the output should also be printed as CSV data.
Example ¶
Totaling the output of “ls -l” shows that the sources for this program currently total 3,892 bytes:
% ls -l total 16 -rw-r--r-- 1 rsc primarygroup 35 Oct 29 08:20 go.mod -rw-r--r-- 1 rsc primarygroup 3857 Oct 29 08:48 total.go % ls -l | total ~ 18 rsc primarygroup 3892 Oct 58 ~ ~ %
