Invalid null command

thegolum35 · Apr 17, 2011

HI,

I'm having trouble with this command running on FreeBSD 8.2, [cmd=]arpspoof -i wlan0 -t 192.168.1.53 192.168.1.1 & > /dev/null[/cmd] it returns

Code:

Invalid null command

How can I solve this issue?

Thanks, Gollum

Remove the ampersand (&).

Or put the ampersand after > /dev/null since the redirection is part of the command you want to run in the background.

Unless you want to redirect both stdin/stdout to /dev/null, in which case you would write >&/dev/null. It's a world full of possibilities
