The root directory is /
Home directory is assigned to you when your account is added. It might be something like /home/hinman /export/home/hinman or something like that. Each user gets a home directory.
/export/home/hinman has a parent called /export/home
/export/home has a parent called /export
/export has a parent called /
/ does not really have a parent, but it acts as it's own parent.
With many shells you can use ~ as a shortcut for /export/home/hinman but if I use ~ it would be /export/home/perderabo (or whatever our home directories really are). We both can use ~joe to refer to joe's home directory.
Every directory must have two special entries called . and ..
. is the current directory
.. is the parent directory
So if you are in /usr/local/bin, . is /usr/local/bin and .. is /usr/local. Unlike ~ these really are in the directory and will work with any shell.

NAME
unburden-home-dir - unburdens home directories from caches and trashes
SYNOPSIS
unburden-home-dir [ -n | -u | -f filter ]
unburden-home-dir ( -h | --help | --version )
DESCRIPTION
unburden-home-dir unburdens the home directory from files and directory which cause high I/O or disk usage but are neither important if
they are lost, e.g. caches or trash directory.
When being run it moves the files and directories given in the configuration file to a location outside the home directory, e.g. /tmp or
/scratch, and puts appropriate symbolic links in the home directory instead.
OPTIONS
-f just unburden those directory matched by the given filter (a perl regular expression) -- matches the already unburdened directories
if used together with -u.
-F Do not check for files in use with lsof before (re)moving files.
-n dry run (show what would be done)
-u undo (reverse the functionality and put stuff back into the home directory)
-h, --help
show this help
--version
show the program's version
