Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b". (Files are by default listed in columns and sorted vertically.) dircolors: Set up color for ls: install: Copies files and set attributes ln: Creates a link to a file ls: Lists the files in a directory mkdir ...
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 ).
View of the root directory in the OpenIndiana operating system. In a computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most directory in a hierarchy. [1] It can be likened to the trunk of a tree, as the starting point where all branches originate from.
The filesystem appears as one rooted tree of directories. [1] Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in DOS and Windows: each drive has a drive letter that denotes the root of its file system tree), such volumes can be mounted on a directory, causing the volume's file system tree to appear as that directory ...
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.
If a directory is writable and has S_ISVTX (the sticky bit) set, files within that directory can be removed or renamed only if one or more of the following is true (see unlink(2) and rename(2)): the user owns the file, the user owns the directory, the file is writable by the user, the user is a privileged user.

Inodes do not contain their hard link names, only other file metadata. Unix directories are lists of association structures, each of which contains one filename and one inode number. The file system driver must search a directory for a particular filename and then convert the filename to the correct corresponding inode number.
