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
