NAME

       zerofill - clear unused disk space and blank devices.

SYNOPSIS

       zerofill [options] [devices] ...

DESCRIPTION

       This command is a relative of nullfile.  Like nullfile, it can be used to write all unused disk space with '0', thereby making file systems
       that are stored on virtual machines easier to pack.  In addition, zerofill can fill unused disk space  with  random  data  before  zeroing,
       which  can be useful to remove forensic trace of deleted files.  Finally, zerofile can be told to operate on and zero (erase) complete disk
       devices.

OPTIONS

       --random=count
              Number of passes to use writing random data before wiping data.

       --help Outputs help screen for the user.

NAME

       args - manipulate and output command arguments.

SYNOPSIS

       args [options] args...

DESCRIPTION

       This  command  is  used to manipulate and echo command line arguments to standard out.  This can include adding quotes around each argument
       passed or a separator, or to output each argument on a separate line.  The program source also offers a basic example of how to	use  shell
       argument parsing and localization in ucommon.

OPTIONS

       --delim=char
	      Set a deliminator character, such as ',', to use between each argument when outputing arguments.

       --directory
	      If argument is a directory, list directory contents as arguments.

       --follow
	      If argument is a directory and a symlink, follow symlinks recursively.

       --lines
	      Output each argument on a separate line.

       --quote=char|pair
	      Set  a  quote or special leading and trailing pair of characters to surround each argument with when output.  A typical use might be
	      --quote=() to surround arguments in parenthesis.

       --recursive
	      If argument is a directory, recursively scan directory and any subdirectory contents as arguments.

       --reverse
	      Reverse order of arguments.

       --help Outputs help screen for the user.
