Compile with:
    gcc $CFLAGS -o ones ones.c
or
    gcc $(portageq envvar CFLAGS) -o ones ones.c

and use/test e.g. like

    ./ones | dd of=/dev/null bs=8M count=1000 iflag=fullblock

[..]

I got it to compile, at least it created a file named ones anyway.  What
I'm unclear about, where is the if= for dd in the command?  All the
commands I've seen before has a if= and a of=.  The if for input and of
for output or target.

==== man 1 dd ====
       if=FILE
              read from FILE instead of stdin
[..]
       of=FILE
              write to FILE instead of stdout
====

note the stuff after 'instead' ;)

So it is piped in with the | thingy?  Got it.  



      

        
I'm assuming that if I want to target sdb, I'd
replace null with /dev/sdb. 


      

      
Yes.



      

        
As I've posted before, even my scripting skills are minimal.  Surprised
I got it to compile even.


      

      
Well, you could copy & paste and on gentoo, there is bound to be a
'gcc' ;)


    

    

    Yea, just my skills on that sort of thing is minimal or none.  I do
    copy and paste pretty well tho.  ;-)  

    

    

    

      

      

        
something.  I placed all this in the /root directory.  I'm assuming I
can copy paste the commands above while in /root to make it work?


      

      
Yes. Or put 'ones' in /root/bin/ or even /usr/local/bin. Depending on
if you expect to use the program later on. But if it's just for this
once it's fine in /root/ alongside the sourcecode.

HTH,
-dnh



    

    

    

    Well, I made notes in my frequent commands file.  It may be rare
    that I use it but when I do, maybe the notes will help.  Maybe.  ;-)
    

    

    Thanks much.
