I have seen exactly this behaviour running find locally. It has always
bugged me, even though it works. Now I have the solution: use the find
-depth flag.
What is going on is that:
(1) find locates a matching directory
(2) runs your arbitrary command on it
(3) descends into the matching directory looking for more matching
directories.
Unfortunately, because (2) removes the directory, (3) fails. The find
continues, but returns a failure error code. The solution is to add
-depth as the first non-path argument to find to cause it to process the
contents of each directory before the directory itself (i.e. depth first).
For example:
$ mkdir -p a/b
$ find . -name a -exec rm -rf {} \;
find: `./a': No such file or directory
$ echo $?
1
(Return code 1 is a failure.)
$ mkdir -p a/b
$ find . -depth -name a -exec rm -rf {} \;
$ echo $?
0
(Return code 0 is a success.)
Success!
