dir (command) 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 ).
APPEND. Sets the path to be searched for data files or displays the current search path.

The cd command can be used to change into a subdirectory, move back into the parent directory, move all the way back to the root directory or move to any given directory. Consider the following subsection of a Unix filesystem, which shows a user's home directory (represented as ~) with a file, text.txt, and three subdirectories.
A symbolic link contains a text string that is automatically interpreted and followed by the operating system as a path to another file or directory. This other file or directory is called the "target". The symbolic link is a second file that exists independently of its target. If a symbolic link is deleted, its target remains unaffected.
