A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
A special system-wide environment variable found on Windows NT and its derivatives. Its value is the location of the current user's profile directory, in which is found that user's HKCU registry hive (NTUSER).

This can be useful if the user's shell's internal code can't deal with the directory they are in being recreated; running cd . will place their shell in the recreated directory. cd ~username will put the user in the username's home directory. cd dir (without a /) will put the user in a subdirectory; for example, if they are in /usr, typing cd ...
Some operating systems restrict a user's access only to their home directory or project directory, thus isolating their activities from all other users. In early versions of Unix the root directory was the home directory of the root user, but modern Unix usually uses another directory such as /root for this purpose.
In Linux, corresponds to a procfs mount. Generally, automatically generated and populated by the system, on the fly. /root: Home directory for the root user. /run: Run-time variable data: Information about the running system since last boot, e.g., currently logged-in users and running daemons.
Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/realdir pwd -L: Display the current working directory logical path - with symbolic link name, if any. Example: If standing in a dir /home/symlinked, that is a symlink to /home/realdir, this would show /home/symlinked
You can store this directory almost anywhere ... on your hard drive, on a floppy, or a USB dongle device. Click on "Tux", the little penguin in the task bar at the bottom of the screen, pick "Configure" from the menu and then "Create Persistent Disk Image". You'll get a list of choices of where to store your Persistent/home directory file.
In Unix-like operating systems, find is a command-line utility that locates files based on some user-specified criteria and either prints the pathname of each matched object or, if another action is requested, performs that action on each matched object.
