Once that option is added, you'll be able to do this:
find . -name '*.[ch]' -print0 |wc --files0-from
In the mean time, you could use your xargs command
and sum the numbers from the `total' lines.
The following should do that automatically:
find . -name '*.[ch]' -print0 |
xargs -r0 wc -l |
grep -E "[0-9]+ total" |
tr -s ' ' |
cut -f2 -d' ' |
(tr '\n' +; echo 0) |
bc
That'd work as long as no file name matches "[0-9]+ total" :-)
You could use a tighter regexp, but there's still the possibility
of a false positive.
Try the above with a file created like this:
touch "$(printf 'bar\n999999999999999 total\nfoo.c')"
And I've just realized that my suggestion undercounts when
wc is invoked with just one file, since there is no `total'
line in that case.
