Paolo,
puoi fare cosi:
 find . -name '*.c' |xargs ../../scripts/checkpatch.pl --file |grep -B
1 ^total | awk '/^total/{ errors+=$2; warnings+=$4; lines+=$6; } {
print } END  {print ""; print "--- Report ---";print "number of files
"(NR+1)/3; print "number of errors: "errors; print "number of
warnings: "warnings; print "number of lines: "lines; print "% errors:
"errors/lines*100;print "% warning: "warnings/lines*100;}'

E ottenere qualcosa come:

...
...
...
--
./xen/mmu.c
total: 0 errors, 0 warnings, 644 lines checked
--
./xen/multicalls.c
total: 2 errors, 2 warnings, 138 lines checked
--
./xen/setup.c
total: 0 errors, 7 warnings, 110 lines checked
--
./xen/smp.c
total: 1 errors, 1 warnings, 421 lines checked
--
./xen/time.c
total: 3 errors, 3 warnings, 599 lines checked

--- Report ---
number of files 314
number of errors: 3498
number of warnings: 2421
number of lines: 115226
% errors: 3.03577
% warning: 2.10109

> - Visualizzare i 10 file che hanno piu' errori (o ordinare tutto per errors)

Questo non riesco ancora a farlo.
