Hi! I have have made two additions to the du utility that I thought you might want to take a look at.
First. The addition of a -p flag. When this is used the file's size in
percent relative to the total number of shown files will be printed. A
downside to this is that du has to go through all files first before it
can start producing output, thus making it silent for a moment.
Example:
% src/du -p /Users/kim/temp/fileutils-4.1.11/tests/
3.94% /Users/kim/temp/fileutils-4.1.11/tests/chgrp
4.33% /Users/kim/temp/fileutils-4.1.11/tests/chmod
3.15% /Users/kim/temp/fileutils-4.1.11/tests/chown
11.81% /Users/kim/temp/fileutils-4.1.11/tests/cp
...
Second. The three kinds of output flags -kmbB, -hH and -p can now be
given simultaneously and will all output their respective data followed
by a tab. -kmb will print first, then -hH and last -p.
Like this:
% src/du -p /Users/kim/temp/fileutils-4.1.11/tests/
40 40K 3.94% /Users/kim/temp/fileutils-4.1.11/tests/chgrp
44 44K 4.33% /Users/kim/temp/fileutils-4.1.11/tests/chmod
32 32K 3.15% /Users/kim/temp/fileutils-4.1.11/tests/chown
120 120K 11.81% /Users/kim/temp/fileutils-4.1.11/tests/cp
...
or:
% src/du -bh /Users/kim/temp/fileutils-4.1.11/tests/
40960 40K /Users/kim/temp/fileutils-4.1.11/tests/chgrp
45056 44K /Users/kim/temp/fileutils-4.1.11/tests/chmod
32768 32K /Users/kim/temp/fileutils-4.1.11/tests/chown
122880 120K /Users/kim/temp/fileutils-4.1.11/tests/cp
...
or:
% src/du -p -B 5K /Users/kim/temp/fileutils-4.1.11/tests/
8 3.94% /Users/kim/temp/fileutils-4.1.11/tests/chgrp
9 4.33% /Users/kim/temp/fileutils-4.1.11/tests/chmod
7 3.15% /Users/kim/temp/fileutils-4.1.11/tests/chown
24 11.81% /Users/kim/temp/fileutils-4.1.11/tests/cp
...
Included is a diff file that was made with du.c of version 4.1.11 of the
GNU Fileutils. If you want one that was made with the latest stable
(4.1) instead I will more than gladly send one over.
I have tried to adhere to the GNU coding standards as thoroughly as
possible and commented the code where I thought needed. I also wrote a
ChangeLog entry to clarify code changes.
ChangeLog:
2002-09-18 Kim Ahlstrom <[EMAIL PROTECTED]>
Added -p flag that prints percentage of file's size relative to all
printed
files' size. New output handling.
* src/du.c: Added global variables to handle the new -p flag and
output options.
(print_size): Rewrite to allow output from both the -kmb flags,
the -hH flags and the new -p flag at the same time. Added code to
accumulate
data for percentage calculation (-p flag).
(du_files): Print files and data accumulated by percentage
calculation (-p flag).
(main): Added -p flag switch-case. Modified h,H,k,m,b,B
switch-cases to allow
the -h and -H flags being active while either -kmbB flags are active.
(usage): Explain -p flag.
If you have any questions I will be more than happy to answer!
Best Regards
Kim Ahlstrom
