[ale] making empty files

[Chris Fowler]

Interesting..
[cfowler at minime cfowler]$ dd if=/dev/zero of=testf bs=1024k count=1
[cfowler at minime cfowler]$ ls -l testf 
-rw-r--r--   1 cfowler  devel     1048576 Mar 18 19:15 testf
[cfowler at minime cfowler]$ dd if=/dev/zero of=testf bs=1024k count=1
seek=20
[cfowler at minime cfowler]$ ls -l testf
-rw-r--r--   1 cfowler  devel    22020096 Mar 18 19:15 testf
[cfowler at minime cfowler]$ du -h testf
2.0M    testf

There is a file that has 1mb in front, 20mb of nothing, than 1mb in the
back.

That is how to create an empty file
