### Normalise time series and/or compute mean, standard deviation

`rms [-a -v -o` outfile`-l# -x# -c# -V# -h]` file(s)

> `-a` subtract average
> `-v` subtract mean, normalise to unit variance
> `-l` number of values to be read (all)
> `-x` number of values to be skipped (0)
> `-c` column to be read (1 or file,#)
> `-o` output file name, just `-o` means file`_a` (if -a), file`_v` (if -v)
> `-V` verbosity level (0 = only fatal errors)
> `-h` show this message

Prints mean, standard deviation, minimal and maximal value of time series. Optionally subtracts mean and normalises to unit variance. Output file file`_a` (if `-a` is set) or file`_v` (if `-v` is set).
