Writing "find" code in C
I've got a project that writing "find" C code in solaris.

That is finding a file in current and sub directories.

While I am looking for some example on the book for two days, but I have no idea where to start.

I think I need to use recursion, but is it true?

I am still a Unix beginner and the teacher and book didn't give me enough info...

Please tell me the way of structure and concept.

Thanks in advance.

We have some rules here. And one of them says:

(6) Do not post classroom or homework problems.

However, because this is a tough problem, I'm going to give you some hints.

Yes, you will ultimately need recursion. But it might make sense to write an ls program first.

Use opendir() and readdir() and closedir() to read the directory entries. For each entry call lstat() to get information about the file. Now you have enough info to write an ls type program.

Eventually, you will want to recurse if you find a directory entry. That should be enough hints to get you going.
