Directories are used to organize files. To create a directory, you use the mkdir command. To delete a directory, you use the rmdir command. To move a file to a different directory, you use the mv command.
Files are used to store data. To create a file, you use the touch command. To delete a file, you use the rm command. To open a file, you use the cat command. To write to a file, you use the echo command.
The Unix file system also has a number of special files, such as device files and symbolic links. Device files are used to access devices such as terminals, printers, and mice. Symbolic links are used to create shortcuts to other files or directories.
