du - Disk Usage for only files and NOT directories.
Hello,
Could any one help me how to find the Disk Usage for all the files in the running directory and the sub directories without the disk usage of the directory. I mean to say, i need only the file names without the size of the directories.
See, i used this command
du -a .|sort -nr|more
here i'm getting even the size of directories. I need only the files in each directory. Could you help me please. Thanks in advance.
Note: I'm using MP-RAS and i find du -l doesn't work out.
------------------------------------
Like to add some more..
I found that ls -lu gives the files in the order that they were accessed (even if it is read and not modified). I'm trying to find some command or simple logic where i can filter the filenames that are large in size and NOT accessed for a longer duration of time.
Even a discussion or clue will also be appreciated. (but it should be genuine please).
Thanks a lot.

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.
-r Read-only mode. This will disable the built-in file deletion feature.
-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.
KEYS
? Show help + keys + about screen
up, down j, k
Cycle through the items
right, enter, l
Open selected directory
left, <, h
Go to parent directory
n Order by filename (press again for descending order)
s Order by filesize (press again for descending order)
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. Percentage is relative to the size of the current directory, graph is rela-
tive 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 directories,
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 versions 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 direc-
tory (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
