Bob has already explained the idea of Gentoo and I can only add that there
is a huge
difference beetween using code created be someone (downloading, compiling,
installing)
and digging in the code on my own :-)

So the tips how should I use gdb were really heplful.
Here is the output
k13 coreutils-5.94 # gdb -x <( printf "run\nbt" ) --args
src/shred --remove --zero adam adam1

My problem is that every time I try it when I try to run this failing
command for the second time it stops
k13 coreutils-5.94 # ps aux | grep shred

zero adam adam1
in state D but I do not know how to resume it, I also cannot kill it. I have
to reboot my server every 5 minutes to give it another try :-)

What should I do next?

Best regards,
Adam
