More like insufficient information in the question, so I answered the typical case. Should the OP answer me the following questions and specify the target shell, I'll provide.

• Should directory "." be included? (I assumed no)
• Should directory ".." be included? (I assumed no)
• Should other directories be included? (I assumed yes)
• Should other non-plain files be included? (I assumed yes)
• Should other hidden files be included? (I assumed no)
• Should subdirectories be visited recursively? (I assumed no)
