NAME

st - simple statistics from the command line interface (CLI)

DESCRIPTION

st is a command-line tool to calculate simple statistics from a file or standard input.

USAGE

st [options] [input_file]

OPTIONS

FUNCTIONS

--N|n|count           # sample size
--min                 # minimum
--max                 # maximum
--mean|average|avg|m  # mean
--stdev|sd            # standard deviation
--stderr|sem|se       # standard error of mean
--sum|s               # sum of elements of the sample
--variance|var        # variance

The following options require that the whole dataset is stored in memory, which can be problematic for huge datasets:

--q1                  # first quartile
--median|q2           # second quartile, or median
--q3                  # third quartile
--percentile=f        # percentile=<0..100>
--quartile=i          # quartile=<1..4>

If no functions are selected, st will print the default output:

N     min  max  sum  mean  stddev

You can also use the following predefined sets of functions:

--summary   # five-number summary (min q1 median q3 max)
--complete  # everything

FORMATTING

--format|fmt|f=<value>  # default: "%g"

Examples of valid formats:

    %d    signed integer, in decimal
    %e    floating-point number, in scientific notation
    %f    floating-point number, in fixed decimal notation
    %g    floating-point number, in %e or %f notation

--delimiter|d=<value>   # default: "\t"

--no-header|nh          # don't display header
--transpose-output|to   # switch rows and columns

INPUT VALIDATION

By default, st skips invalid input with a warning.

You can change this behavior with the following options:

--strict   # throws an error, interrupting process
--quiet|q  # no warning
