+NAME
+       ncdu - NCurses Disk Usage
+
+
+SYNOPSIS
+       ncdu [-hqvx] [--exclude PATTERN] [-X FILE] dir
+
+
+DESCRIPTION
+       ncdu  (NCurses  Disk Usage) is a curses-based version of the well-known
+       'du', and provides a fast way to see what directories  are  using  your
+       disk space.
+
+
+OPTIONS
+       -h     Print a small help message
+
+       -q     Quiet  mode.  While calculating disk space, ncdu will update the
+              screen 10 times a second by default, this will be  decreased  to
+              once  every  2  seconds  in quiet mode. Use this feature to save
+              bandwidth over remote connections.
+
+       -v     Print version.
+
+       -x     Only count files and directories on the same filesystem  as  the
+              specified dir.
+
+       --exclude PATTERN
+              Exclude  files  that  match  PATTERN. This argument can be added
+              multiple times to add more patterns.
+
+       -X FILE, --exclude-from FILE
+              Exclude files that match any pattern in FILE. Patterns should be
+              separated by a newline.

+
+       a      Toggle between showing disk usage and showing apparent size.
+
+       d      Delete  the selected file or directory. An error message will be
+              shown when the contents of the directory do not match or do  not
+              exist anymore on the filesystem.
+
+       t      Toggle dirs before files when sorting.
+
+       g      Toggle  between  showing  percentage, graph, both, or none. Per-
+              centage is relative to the size of the current directory,  graph
+              is relative to the largest item in the current directory.
+
+       e      Show/hide  'hidden'  or 'excluded' files and directories. Please
+              note that even though you can't see the hidden files and  direc-
+              tories,  they are still there and they are still included in the
+              directory sizes. If you suspect that the  totals  shown  at  the
+              bottom  of  the  screen  are  not correct, make sure you haven't
+              enabled this option.
+
+       i      Show information about the current selected item.
+
+       r      Refresh/recalculate the current directory.
+
+       q      Quit

+
+HARD LINKS
+       Every disk usage analysis utility has its own  way  of  (not)  counting
+       hard links.  There does not seem to be any universally agreed method of
+       handling hard links, and it is even inconsistent among  different  ver-
+       sions of ncdu. This section explains what each version of ncdu does.
+
+       ncdu  1.5  and  below  does not support any hard link detection at all:
+       each link is considered a separate inode and its size  is  counted  for
+       every link. This means that the displayed directory sizes are incorrect
+       when analyzing directories which contain hard links.
+
+       ncdu 1.6 has basic hard link detection: When a  link  to  a  previously
+       encountered  inode  is  detected, the link is considered to have a file
+       size of zero bytes.  Its size is not counted again,  and  the  link  is
+       indicated  in  the  browser  interface  with  a 'H' mark. The displayed
+       directory sizes are only correct when all  links  to  an  inode  reside
+       within  that directory. When this is not the case, the sizes may or may
+       not be correct, depending on which links were considered as "duplicate"
+       and  which  as  "original". The indicated size of the topmost directory
+       (that is, the one specified on the command line upon starting ncdu)  is
+       always correct.
+
+       ncdu 1.7 has improved hard link detection. Each file that has more than
+       two links has the "H" mark visible in the browser interface. Each  hard
+       link  is  counted  exactly  once for every directory it appears in. The
+       indicated size of each directory is therefore, correctly,  the  sum  of
+       the  sizes  of  all  unique inodes that can be found in that directory.
+       Note, however, that this may not always be same as the space that  will
+       be  reclaimed after deleting the directory, as some inodes may still be
+       accessible from hard links outside it.
+
+
+BUGS
+       Directory hard links are not supported. They will not  be  detected  as
+       being hard links, and will thus be scanned and counted multiple times.
+
+       Some  minor  glitches may appear when displaying filenames that contain
+       multibyte or multicolumn characters.
+
+       Please report any other bugs you may find at the bug tracker, which can
+       be found on the web site at http://dev.yorhel.nl/ncdu
