Subject: [PATCH] commands/ls: Print ???????????? if unable to get file size
Date: Mon, 14 Aug 2023 01:20:29 -0500	[thread overview]
Message-ID: <20230814062029.1859249-1-development@efficientek.com> (raw)

In long list mode, if the file can not be opened, the file is not printed.
Instead, print the file but print the size as ????????????.
