[Chris is explaining why Berkeley UNIX systems allow onlyto change a file's ownership. If you need to change ownership, there is a . - JP]
mkdir .hide; chmod 700 .hide cd .hide create_huge_file >foo chown prof1 foo create_huge_file >bar chown prof2 bar create_huge_file >baz chown prof3 baz
All you would need do is find someone with a high quota or no quota (such as a professor) who does not often check his own usage (such as a professor) and probably does not care that the disk is 99 percent full (such as a, er, well, never mind), and then give away files as necessary to keep under your own quota. You could regain ownership of the file by copying it to another disk partition, removing the original, and copying it back.
