Like to be able to use sed to add new line after line match

Been looking around for this but haven't been able to find anything.

I'd like to be able to add a new line after matching text in a line.

For example, say I got:

Code:

---

#output databases: mysql, snort, password yourpassword, more, blah

---

and after this line I'd like to add:

Code:

---

#output databases: mysql, snort, password yourpassword, more, blah
darn right

---

So far I got:

Code:

---

sed -i -e 's`^#output database$`#out$ \
darn right`g' file

---

As you can see I'm at a loss as what the second value should be. I'd like to be able to match this generically. Is this possible? Also does the first value (^output database$) appear right?

Ah i got it (Gentoo Developer's guides are awesome):

Code:

---

sed -i -e `^text to match$/a text to add on new line` file

---

Gotta like sed, Doh!

Thanks :D
Btw heads up, the forwardslash has been removed in the above but the link is good :D
