find のオプションへ -path ‘dir’ -prune を付加すると、これは -path ‘dir’ に適合したものを結果から -prune (刈り取る) 意味がある。しかし -path ‘dir’ の dir の指定のしかたによって、実際に刈り取られる挙動に変化が出る。以下に例を示す。
- (1) find . -path ‘./ryuichi/kawamura’ -prune -o -print
- (2) find . -path ‘./ryuichi/kawamura/’ -prune -o -print
- (3) find . -path ‘./ryuichi/kawamura/*’ -prune -o -print
これらの違いは以下。
- (1) の場合、 kawamura 自身を含め、 kawamura 以下全部が刈り取られる。
- (2) の場合、これは -path … -prune を指定しないのと全く同じ結果になる (刈り取られない) 。
- (3) の場合、 kawamura 自身は現れるが、 kawamura 以下全部が刈り取られる。
