Inputting with sed, based on matched pattern


Hi,

I want to know if you can input with sed but instead of specifing a line number like below I wan't to be able to insert based on a specific word or patttern.

Code:
10i\

This line will be inserted before each line
is this possible with sed or should I use AWK?

Thanks

Mike

Code:
/match/ { i\
this
}
Code:
perl -pe 'print "THIS\n" if /match/'

Thansk Billy, the sed script was exactly what I was looking for, i figured it would be like AWK /pattern/ match but I wasnt using the curly brackets in my script.

Hi, thanks again, how do you mean? a "V" like for encapsulation?
