How to export some lines from a file to a new file?

Dear everyone,
I have a big file with many information in it, but I just want some lines.
I don't know exactly what the number of the line I want, I only know some part of these line. It all starts with the word 'F(tot :1 )'
I use grep command and find it. It looks like that on the screen:
F(tot :1) 3 4 5
F(tot :1) 68 7 8
and so on.
I want to insert all lines which I found from the grep command to a new file.
Could you guys please help me how to do it?
I tried google but it doesn't help.
Thanks a lot

Thanks so much but I still can not get it.
I write the command like that:
grep 'F(tot: 1' ft.09 F1.txt
'ft.09' is the old file, F1.txt is the new one.
Is the command right?

Sorry if the question is so stupid.

I did it!
Thanks a lot.

Before I made a mistake.
I created the file F1.txt before the grep command.
Sorry for bothering

Using Elixir's code you don't need to create file before grep.

grep 'F(tot:  1' ft.09 > F1.txt

If you want to append data into the file then just use >> instead of >.Smilie
