where is the problem in my sed command....

for example i have the file that contain several line..and i want to swap the first word and the second word than i store it into new file..

on the command i wrote:


Code:
sed -e "s/^\([^]*\)\([^]*\)/\2\1/g" file > swapfile

i think its already correct...
but i got the error


Code:
sed: -e expression #1, char 26:invalid reference \2 on 's' command's RHS

actually whats wrong with this? i am very exhausted...
