PROGRAM:
NAME
total - sum up columns
SYNOPSIS
total [ -m ][ -sE | -p | -u | -l ][ -i{f|d}[N] ][ -o{f|d} ][ -tC ][ -N [ -r ]] [ file ..
]
DESCRIPTION
Total sums up columns of real numbers from one or more files and prints out the result on
its standard output.
By default, total computes the straigt sum of each input column, but multiplication can be
specified instead with the -p option. Likewise, the -u option means find the upper limit
(maximum), and -l means find the lower limit (minimum).
Sums of powers can be computed by giving an exponent with the -s option. (Note that there
is no space between the -s and the exponent.) This exponent can be any real number,
positive or negative. The absolute value of the input is always taken before the power is
computed in order to avoid complex results. Thus, -s1 will produce a sum of absolute
values. The default power (zero) is interpreted as a straight sum without taking absolute
values.
The -m option can be used to compute the mean rather than the total. For sums, the
arithmetic mean is computed. For products, the geometric mean is computed. (A
logarithmic sum of absolute values is used to avoid overflow, and zero values are silently
ignored.)
If the input data is binary, the -id or -if option may be given for 64-bit double or
32-bit float values, respectively. Either option may be followed immediately by an
optional count, which defaults to 1, indicating the number of double or float binary
values to read per record on the input file. (There can be no space between the option
and this count.) Similarly, the -od and -of options specify binary double or float
output, respectively. These options do not need a count, as this will be determined by
the number of input channels.
A count can be given as the number of lines to read before computing a result. Normally,
total reads each file to its end before producing its result, but this behavior may be
overridden by inserting blank lines in the input. For each blank input line, total
produces a result as if the end-of-file had been reached. If two blank lines immediately
follow each other, total closes the file and proceeds to the next one (after reporting the
result). The -N option (where N is a decimal integer) tells total to produce a result and
reset the calculation after every N input lines. In addition, the -r option can be
specified to override reinitialization and thus give a running total every N lines (or
every blank line). If the end of file is reached, the current total is printed and the
calculation is reset before the next file (with or without the -r option).
The -tC option can be used to specify the input and output tab character. The default tab
character is TAB.
If no files are given, the standard input is read.
EXAMPLE
To compute the RMS value of colon-separated columns in a file:
total -t: -m -s2 input
To produce a running product of values from a file:
total -p -1 -r input
