/me points to grep's -z and -Z option
There is also the possibility to plug in tr in between:
find ... -print | do someting | do something ... \
tr '\n' '\0' \
xargs -0 command
I'd strongly advise against this hack (actually any use of xargs
without -n) on untrusted directories as it will break dangerously
with filenames containing newline.
