Awk redirect command output

Question

I need to redirect the output to a file and add the date and time. I try this:

make all | awk '{ print strftime("%Y-%m-%d %H:%M:%S"), $0; }' > file 

I expect:

 2011-12-13 15:00:50 compilation.... 2011-12-13 15:00:52 still compilation 2011-12-13 15:00:55 compilation ... 

How can i do this? If I delete the "> file" on the screen, I see the correct output. But I will redirect this to a file.

Can someone help me?

Try the tee command as follows:

 make all | awk '{ print strftime("%Y-%m-%d %H:%M:%S"), $0; }' | tee file 

tee will map the output to STDOUT and save the output to a file.
