Fouth line to end of file:

    perl -ne 'print if 4 .. eof' file
[download]

Fifth line to tenth:

    perl -ne 'print if 5 .. 10' file
[download]

Note, in the first example the eof if mainly a visual indicator. The following would work just as well:

    perl -ne 'print if 4 .. 1' file
    perl -ne 'print if 4 .. 0' file

    # or
    perl -ne 'print if $. >= 4' file
[download]
