Splitting a file based on positive and negative numbers

Dear All,
I have to split a tab delimited file in two files based on the presence of a positive or negative in column number 9 , for example

Code:
file:
A  1   5   erg   +   6766   0.9889  0.9817   9.01882 erg inside upstream
B  1   8   erg2   +   6766   0.9889  0.9817   -9.22 erg2 inside downstream

file1:
A  1   5   erg   +   6766   0.9889  0.9817   9.01882 erg inside upstream

file2:
B  1   8   erg2   +   6766   0.9889  0.9817   -9.22 erg2 inside downstream

any hint?
thanks,
paolo

NAME
ng_UI -- UI netgraph node type SYNOPSIS
#include <netgraph/ng_UI.h> DESCRIPTION
The UI node type has two hooks, upstream and downstream. Packets received on downstream must have 0x03 (indicating unnumbered information) as their first byte; if not the packet is dropped. This byte is then stripped and the remainder of the packet sent out on upstream. Conversely, packets received on upstream will have a 0x03 byte prepended to them before being forwarded out on the downstream hook. HOOKS
This node type supports the following hooks: downstream Downstream connection. Packets on this side of the node have a 0x03 as their first byte. upstream Upstream connection. Packets on this side of the node have the initial 0x03 byte stripped off. CONTROL MESSAGES
This node type supports only the generic control messages. SHUTDOWN
This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when both hooks have been disconnected. SEE ALSO
netgraph(4), ngctl(8) HISTORY
The ng_UI node type was implemented in FreeBSD 4.0. AUTHORS
