find first 100kb file and then "man dd"

You could use dd to create the 100k file by sourcing /dev/urandom

mkfile
Usage: mkfile [-nv] <size>[g|k|b|m] <name1> [<name2>] ...

Bug
Hi:
There's a little known device called /dev/zero which can quickly create a file of known size. This command:

dd if=/dev/zero of=myfile bs=1024 count=10

creates file "myfile" filled with zeros with a block size of 1000 muliplied 10 tens or 10K.
