pathname. . .]
Follow a pathname until a terminal point is found (e.g., a file, directory, char device, etc.). If namei finds a symbolic link, it shows the link and starts following it, indenting the output to show the context. namei prints an informative message when the maximum number of symbolic links this system can have has been exceeded.
Show mode bits of each file type in the style of ls (e.g.,"rwxr-xr-x”).
Show mountpoint directories with a D rather than a d.
For each line of output, namei prints the following characters to identify the file types found:
A regular file.
An error of some kind.
A block device.
A character device.
The pathname namei is currently trying to resolve.
A symbolic link (both the link and its contents are output).
