A recursive call quesion

I am writing a ls-like command in unix and I have some troubles when implementing ls -R call.

Currently, my output is something like

file1
file2
sub-directory1
file3 in sub-directory1
file4 in sub-directory1
file5
sub-directory2
file6 sub-directory2

But ls -R output is:

file1
file2
file5

sub-directory1
file3 in sub-directory1
file4 in sub-directory1

sub-directory2
file6 in sub-directory2

I think I made some mistakes in the recursive call. Any help?

Thanks

Hi tiger0516,

Without seeing your code, I suspect that you're processing the files/directories in the current directory in the order that you encounter them.

You'll need to "save" the directories in a table as you encounter them and list the files. Then process the list of directories.

Or save both in a list, process the directories, then process the files.

Good Luck!

Yes, I did so

Do you mean a table for all directories? But, for example, a sub directory may have its own sub directory, and so on. Does that matter? I am confused by recursive call if it involves several steps.
