cdck generated plot-file can't read from gnuplot

[Lödur]

Binary package hint: cdck

o I've burned a CD-RW (4x) with two files (with CD/DVD Creater from Nautilus)
o Now I opened a gnome -terminal and typing the following and press [Enter]:
cdck

---
Reading sectors 1-302800
302800 ok

CD overall:
   Sectors total: 302800:
   Good sectors: 302800:
   Bad sectors (incl. with poor timing): 0
CD timings:
   Minimal = 2 usec (0.000002s)
   Maximal = 181271 usec (0.181271s)
   Average = 776 usec (0.000776s)

Conclusion:
   Satisfactory disc

I've read in the manual page of cdck, that I can save the result in a dat-file to represent it with gnuplot.
But the generated dat-file can't read from gnuplot.

o Now I opened a gnome -terminal and typing the following and press [Enter]:
cdck -p

And then?

My guess:
* You got the file cdck-plot.dat~
* You ran `gnuplot cdck-plot.dat~' and got:

#v+
gregoa@belanna:/tmp$ gnuplot cdck-plot.dat~

0 9
^
"cdck-plot.dat~", line 2: invalid command

gregoa@belanna:/tmp$
#v-

After reading a bit about gnuplot it seems that this is not the way
to actually plot a datafile. What works for me is (plot.dat is a
shortened version of your cdck-plot.dat~):

#v+
gregoa@belanna:/tmp$ gnuplot

gnuplot> q

#v-

Another option would be to add
    plot '-'
as the first line of the datafile and
    end
    pause -1
at the end, then `gnuplot plot.dat' also works; but I'm nor sure the
"pause -1" is what's wanted in each case.

IMO there is no real bug in cdck, but I cann add a note to the manpage
about how to use the datafile.

Hello,

thanks for adding a note to the manpage!

Maybe it's not a critical bug, but it's a stumbling block for John Doe (Otto Normal) like me.

Bye,
