By default, the Single UNIX Specification (SUS) specifies that du is to display the file space allocated to each file and directory contained in the current directory. Links will be displayed as the size of the link file, not what is being linked to; the size of the content of directories is displayed, as expected.

MLST RFC 3659 Provides data about exactly the object named on its command line in a standardized machine-readable format. MODE RFC 959 Sets the transfer mode (Stream, Block, or Compressed).

df (abbreviation for disk free) is a standard Unix command used to display the amount of available disk space for file systems on which the invoking user has appropriate read access. df is typically implemented using the statfs or statvfs system calls .
In a Unix shell, the full stop called the dot command (. ) is a command that evaluates commands in a computer file in the current execution context. [ 1 ] In the C shell , a similar functionality is provided as the source command, [ 2 ] and this name is seen in "extended" POSIX shells as well.
In computer software, specifically the DCL command-line interface of the OpenVMS operating system, the DIRECTORY command (often abbreviated as DIR) is used to list the files inside a directory. [1] It is analogous to the DOS dir and Unix ls commands.
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. [1] It is one of the basic commands to help navigate the file system . The command is usually implemented as an internal command in the command-line interpreter ( shell ).
