                   [input ...]

Monitor the progress of data through a pipe. A Python implementation of the original `pv` command:
functional but not yet feature complete.

positional arguments:
  input                 Input file path. Uses stdin if not specified.

options:
  -h, --help            show this help message and exit
  -p, --progress        Turn the progress bar on.
  -t, --timer           Turn the timer on.
  -e, --eta             Turn the ETA timer on.
  -I, --fineta          Display the ETA as local time of arrival.
  -r, --rate            Turn the rate counter on.
  -a, --average-rate    Turn the average rate counter on.
  -b, --bytes           Turn the total byte counter on.
  -8, --bits            Display total bits instead of bytes.
  -T, --buffer-percent  Turn on the transfer buffer percentage display.
  -A LAST_WRITTEN, --last-written LAST_WRITTEN
                        Show the last NUM bytes written.
  -F FORMAT, --format FORMAT
                        Use the format string FORMAT for output format.
  -n, --numeric         Numeric output.
  -q, --quiet           No output.
  -W, --wait            Wait until the first byte has been transferred.
  -D DELAY_START, --delay-start DELAY_START
                        Delay start.
  -s SIZE, --size SIZE  Assume total data size is SIZE.
  -l, --line-mode       Count lines instead of bytes.
  -0, --null            Count lines terminated with a zero byte.
  -i INTERVAL, --interval INTERVAL
                        Interval between updates.
  -m AVERAGE_RATE_WINDOW, --average-rate-window AVERAGE_RATE_WINDOW
                        Window for average rate calculation.
  -w WIDTH, --width WIDTH
                        Assume terminal is WIDTH characters wide.
  -H HEIGHT, --height HEIGHT
                        Assume terminal is HEIGHT rows high.
  -N NAME, --name NAME  Prefix output information with NAME.
  -f, --force           Force output.
  -c, --cursor          Use cursor positioning escape sequences.
  -L RATE_LIMIT, --rate-limit RATE_LIMIT
                        Limit transfer to RATE bytes per second.
  -B BUFFER_SIZE, --buffer-size BUFFER_SIZE
                        Use transfer buffer size of BYTES.
  -C, --no-splice       Never use splice.
  -E, --skip-errors     Ignore read errors.
  -Z ERROR_SKIP_BLOCK, --error-skip-block ERROR_SKIP_BLOCK
                        Skip block size when ignoring errors.
  -S, --stop-at-size    Stop transferring after SIZE bytes.
  -Y, --sync            Synchronise buffer caches to disk after writes.
  -K, --direct-io       Set O_DIRECT flag on all inputs/outputs.

  -o OUTPUT, --output OUTPUT
                        Output file path. Uses stdout if not specified.
