If you do

find /tmp  -name 'petal_*' -mtime +30 -print0 | xargs -0 rm

then the -print0 for find will make it output \0 (ie the NULL character) as
the file separator instead of \n. -0 for xargs tells it to expect the files
to be separated by \0 instead of \n. This guarantees no funny with ;s or
spaces business because filenames cannot contain \0,
