thanks alot DaveC and RusselB
finally i come out like this, it work fine
Code:
on *:text:whowas*:?: {  
  if ($nick == test) {  whowas $2 }
}
raw 314:*: { /msg test $1- }


But the thing is, it work only with exact the nick i'm input, because on the line raw 314:*: { /msg test $1- }
it wont accept $nick
What do i do, if i want to give that out for more then one nick have power to do that ??

for sample
Code:
on *:text:whowas*:?: {  
  if ($nick == test) {  whowas $2 }
  if ($nick == jimmy) {  whowas $2 }
  if ($nick == tommy) {  whowas $2 }
}
raw 314:*: { /msg $nick $1- }

that what i mean, but it wont work
