shopt -s nullglob

UNBURDEN-HOME-DIR(1)						   User Commands					      UNBURDEN-HOME-DIR(1)

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

EXAMPLES

       Example configuration files can be found at /usr/share/doc/unburden-home-dir/examples on Debian-based systems and in the etc/ directory	of
       the source tar ball.

FILES

       /etc/unburden-home-dir,	 /etc/unburden-home-dir.list,	~/.unburden-home-dir,  ~/.unburden-home-dir.list,  /etc/default/unburden-home-dir,
       /etc/X11/Xsession.d/95unburden-home-dir

       Read /usr/share/doc/unburden-home-dir/README on debianoid installations or README in the source tar ball for an explanation of these files.
