There are a number of ways to view files on Linux, because, after all, files on Linux are multifaceted. They have names, they have content, they have access permissions, and they have dates and times associated with their “birth” (when they were initially added to the file system) as well as when they were last changed and last accessed. This post covers the commands that allow you to view all these details.
The easiest and most obvious way to list files is with the ls command. By default, ls will list files in the current directory in name order, but you can reverse that by adding the -r option.
