When you unlink a file the filesystem should recover the associated disk blocks and inode. I'm assuming that you only want to remove some of the files and, possibly, directories based on some criterion or other. If this is the case, once you have completed your tidy-up you should run

fsck -n /dev/rdsk/c......

which will check the partiton without making any changes and give you some stats at the end including percentage fragmentation. If the fragmentation value is above single figures then consider doing a ufsdump of the partition, remaking it with newfs and doing a ufsrestore -rvf. It is extremely rare in my experience to need to do this.

If on the other hand you actually want to unlink all of the directories and files on the partition, don't bother, just newfs it.

I hope this is useful.

Cheers,
