depends how many other things you want to do at the same time ;)

 var=`sed -n '2p; 2q' file`

 (the "2q" makes sed exit on the second line too, otherwise it'll keep
 going through the rest of the file)

or

 var=`awk 'NR == 2 {print; exit}' file`



just for completeness:

 var=`perl -ne 'if ($. == 2) { print; exit }'`
