DESCRIPTION

       attributes. Several attributes or groups can be specified, separated by comma.

OPTIONS

       The following options are understood:

       -?, --help
	   Prints a short help text and exits.

       -a, --attributes=ATTRIBUTES
	   The attributes to get, specified as a comma-separated list of gvfs file attribute names.

       -h, --hidden
	   Show hidden files.

       -l, --long
	   Use a long listing format.

       -c, --show-completions=PREFIX
	   Show only filenames starting with PREFIX.

       -n, --nofollow-symlinks
