There, not here. Not with my GNU find, which works as expected.

Please, again, try yourself:
Code:
lem@biggy:/tmp$ touch {file,test}{1,2,3}
lem@biggy:/tmp$ find /tmp/*test* -ls
197009    0 -rw-rw-r--   1 lem      lem             0 set  2 20:03 /tmp/test1
197010    0 -rw-rw-r--   1 lem      lem             0 set  2 20:03 /tmp/test2
197011    0 -rw-rw-r--   1 lem      lem             0 set  2 20:03 /tmp/test3
lem@biggy:/tmp$ find /tmp/*test* -exec ls -l '{}' \;
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test1
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test2
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test3
lem@biggy:/tmp$ find /tmp/*test* -exec ls -lr '{}' +
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test3
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test2
-rw-rw-r-- 1 lem lem 0 2012-09-02 20:03 /tmp/test1

Quote:
There is nothing in that find command that prints a matching file name twice (and non-consecutively), and since a directory cannot contain two identically-named files, the shell must be matching one or more directories with that pattern (in addition to *test* files in tmp, if any).
Strange. He run an -exec -ls -l, not an -execdir. And he didn't notice that the files were in different subdirectories!?

Quote:
With a directory path, the -exec predicates of those find commands will list or attempt to delete every regular file in that directory and its subdirectories, regardless of a file's name.
Of course.
So you're saying that his find is working as expected, too. Nice. Smilie

Please, again, try yourself:
I don't need to try anything. Looking at your output, your test results are exactly what I would expect. However, your test is not relevant. Your file layout does not match the OP's (if it does, the sample data in post #3 is wrong).

It seems you have totally missed my point.

Since

can never ever be the output of an
Code:
ls -l

command, we cannot know what the OP has really done and what has been the real output.

In his first post, the OP stated:
Code:
second command it listed all the files inside the directory which including those filename that not *test*

Quote:

We both have made assumption about what has happened. You seem to be sure that the last output in post3 has been something with the names of the files repeated two times... and that the OP missed the different subdirs despite not using -execdir, which is a bit strange.

I assumed that that output has been duplicated by the OP in posting, and that he wrote the truth in his first post. So I just assured him that my find works as expected, not knowing what's going on there.

Re-reading all the thread, you can surely be right.

Very good points.

Add to them that none of the find commands in posts #1 and #3 are syntactically valid: the ; that terminates an -exec ... must be the only character in its argument.
