I'm not sure if it is exactly the same as '-@' in Bert proposal, but
"ack", grep-like text finder in Perl (http://betterthangrep.com or
http://p3rl.org/ack), includes the following command line option:

  --line=NUM

    Only print line NUM of each file. Multiple lines can be given with
    multiple --line options or as a comma separated list
    (--line=3,5,7). --line=4-7 also works. The lines are always output in
    ascending order, no matter the order given on the command line.
