Nope, the cut works just fine. I realise that on some systems, wc(1)
will try to format the output "nicely" (that is so annoying!), so I
could write:

wc -l /var/log/kernel.log | perl -ne '/^\s*(\d+)\s/; printf "%.02f%%
", "$1.0" / 596058.0'

But the bug that caught my attention is still there. :)

David, you get a small beer of your choice. But the 大瓶 is still up for grabs.
