Extract known lines

Hi all,

I have a text file of 143 lines. The I don't want all lines but want to retain line format.

How can I extract lines 34, 65, 68, 70 (plus 7 others) easliy?

I have found some example head/tail n lines and some sed -n examples that have been shown for single line or mass consecutive extractions. What i would idealy like is a one liner that I give the line numbers to extract.

Any hints or examples would be great.

Cheers and beers,

I'd actually use sed
sed -n '5p;10p;20p;51p' testfile

To extract lines 5, 10, 20 and 51 from testfile.
