The concept of "file size" can be a bit tricky. How "long" a file is
and how much disk space a file uses are not necessarily the same.
A fun example,
$ dd of=bigfile if=/dev/zero seek=1000m count=1
1+0 records in
1+0 records out
512 bytes transferred in 0.000240 secs (2132556 bytes/sec)
$ ls -l bigfile
-rw-r--r-- 1 cjc cjc 536870912512 Jan 29 21:44 bigfile
$ du bigfile
40 bigfile
Heh. Have a look at the little blurb in the handbook or FAQ (forget
which) about putting a terabyte file on a floppy for more.
