[GSoC 2008] fs-utils: File system access utilities

["Arnaud Ysmal" <ysmal.arnaud%gmail.com@localhost>]

Hi everyone !

A brief status report of my Google Summer of Code project: fs-utils
(http://netbsd-soc.sourceforge.net/projects/fs-utils/).

Most of the must-have components have been written but still need some more
testing, clean up and optimisation.

The following programs have been implemented : cat, chflags, chmod, chown,
cp, diff, du, ln, ls, mkdir, mkfifo, mknod, mv, rm, rmdir, touch.

An interactive tool has also been written. He allows the use of the commands
described above and adds commands like cd, umask and pwd, so as to browse the
image as if it was mounted.

A short example of what is possible:

/home/stacktic/rump_ffs.img(ffs):/librump/rumpkern # cd
/home/stacktic/rump_ffs.img(ffs):/ # du -hs
5.4M    .

Of course each command can be called separately.

Since the programs only run on NetBSD, I am thinking about trying
to make them run under non-NetBSD operating systems for the second term.
And of course adding new functionnalities :)

The first version of the source code can be fetched from
http://netbsd-soc.sourceforge.net/projects/fs-utils/fs-utils_20080709.tar.gz
and is also available on the cvs.
