dsptop: unrecognized option '--0'

Usage: dsptop [dhlmnpqrsSvy]
See "man dsptop" for more details.
--delay/-d <value>              Set the screen refresh rate in seconds (fractional seconds ok).
--format/-f <text|csv|gnuplot|gnuplot_wxt>
                                 Set the --output file format for DSP usage data, default is text.
                                 A file extension (.txt, .csv, .gp_cmd & .gp_dat) will be appended
                                 to the filename selected with --output. Selecting gnuplot_wxt will
                                 also launch gnuplot with a wxt terminal to plot DSP usage data.
--help/-h                       Display help.
--logging/-l <first|last>       Enable DSP message logging to stdout. DSP messages are captured in a
                                 circular buffer. Selecting "first" will write the DSP messages from
                                 the first full trace buffer to stdout and terminate dsptop. Selecting
                                 "last" forces the trace buffer to operate as a circular buffer in which
                                 case the logging data is written to stdout when dsptop is terminated.
                                 Use --output to select a file for logging rather than stdout.
--maxoutfile/-m <value>         Set the max size in bytes for --output files (default is 0 - infinite).
--number/-n <value>             Set the number of screen update iterations (default is 0 - infinite).
--output/-o <filename>          Select a file for logging (-l) or usage data (-f).
--resolution/-r <value>         Set plot resolution in seconds (fractional seconds ok).
--process/-p                    Switch from continuous DSP run/idle time accumulation to
                                 single DSP process run/idle accumulation. Run/idle time
                                 will stop advancing on exit of the current process and
                                 resume when the next process starts.
--quiet/-q                      Send all stdout to /dev/null except logging data.
--sample/-s <value>             Set the moving average sample window in seconds (fractional seconds ok).
--sync/-y                       Enable sync (used by dsptop_sync script).
--version/-v                    Display version.
