View 10 lines after the 1st occurence of a string

Hi Everyone,

I am looking for the unix command by which I can view 10 lines after the 1st occurence of a string (including the 1st occurence)

Example : I have the following lines in a unix file. I have to look for the 1st occurence of the string "How are you" and then view the next 10 lines from there. What would be the command
Line 1: Hi
Line 2: My Name is Kannan
Line 3: Very good
Line 4: How are you
Line 5: Welcome to Unix Forum
Line 6: Good
Line 7: Learn Many things here
Line 8: Hi
Line 9: Hi
Line 10: Hi
Line 11: Hi
Line 12: Hi
Line 13: Hi
Line 14: Hi
Line 15: Hi

My system is Unix and I am accessing it using Putty

Whats the flavor of unix?
