Displaying specific lines in a file.

I'm trying to figure out how to display a certain line in a text file. I keep getting references to Tail and Head, and I know how these work, but i'm lost on how to find say the third out of the five lines and display only that.

I thought maybe grep could help, but that doesn't seem likely.

Any help is greatly appreciated!

To print the 3rd line of a file:

sed -n '3 p' < filename

Tools using heads and tails...

> cat f1
line 1
line 2
line 3
line 4
line 5

> head -3 f1 | tail -1
line 3

in essence, finding the first three lines of a file, then selecting the last line of what I just found.

I didn't even consider finding first three lines and then the last of those three lines... ingenious D:!
