creating file by 'dd'

[R.L. Reingard]

Hi Lee,

i do want to have a try with the idea of creating a (huge)file and then  
erase it afterwards
so i changed the command to create a small file first, which i could use  
for a test.
how to understand the outcome?

user at ubuntu:~$ dd if=/dev/zero of=/home/user/hugefile bs=1 count='expr  
1024 \* 1'
dd: ungültige Zahl „expr 1024 \\* 1“
user at ubuntu:~$

thank you for help
René
