I am finding myself irritated by solaris 8's lack of du and df -h. Especially now that solaris 9 actually has the flag. So I am preparing to write a small shell one-liner or perl if I cant do it with awk or sed (the principle being, if youre going to do it a bunch of times, you want it to be fast).

So the challenge is:

Replicate the output of a du or df with the -h flag. Example: 

minotaur% df -k | grep c0t1
/dev/dsk/c0t1d0s1    1269615  814811  391324    68%    /usr
/dev/dsk/c0t1d0s3     245407   44583  176284    21%    /var
/dev/dsk/c0t1d0s0     424519  187200  194868    49%    /home
minotaur% df -h | grep c0t1
/dev/dsk/c0t1d0s1      1.2G   796M   382M    68%    /usr
/dev/dsk/c0t1d0s3      240M    44M   172M    21%    /var
/dev/dsk/c0t1d0s0      415M   183M   190M    49%    /home

Replicate it in such a way that it can be passed input from standard in.

Special note: if you can do it in sed or some other shell command (ideally a common one, let's not be linux or solaris or bsd centric here), that is fine, given the intent is to have a working shell alias. Contestants will be judged from the first character after the pipe: 


alias du 'du | perl ... '

So, yeah, that means you get a 1 character bonus for using sed, but I doubt your command would be as compact.

Consider it a Unix "brown bag" golf. Enjoy!
