What command in linux I can raise a window to be infront of other windows, (make it active and infront)...
I dont want to use mouse clicks.. just some linux/unix command line...

only widget i can think of is wmctrl. i'm not sure how flexible it is, but it seems to work under gnome, and is originally for windomaker, so that's quite a gap it's jumped there...

I wrote a small utility to do this a while back. I've recently rewritten it (just yesterday, in fact!) so I can give it a window name. Originally, it required the window id number and I had a shell script to find the id from the name (via 'xwinifo -root -tree' and some grepping), but it was quite slow and didn't allow substring matching. I rewrote it in Python but it was still intolerably slow (took almost a WHOLE second!). Thus, I added the name matching into the C program. You can download the src here.
