change in file requires

Hi,

i have one file, filename -> a.txt, i want that simple way just enter command and it will do that, not through redirection way.

AAAAAAAAAAAAAAAAAAAAAAA

FFFFFFFFFFFFFFFFFFFFFFF

i want to disable line2 like

#BBBBBBBBBBBBBBBBBBBBBBB

and wants to add another line after line4 [ZZZZZZZZZZZZZZZZZZ] so output shows like that.

AAAAAAAAAAAAAAAAAAAAAAA
#BBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDD
ZZZZZZZZZZZZZZZZZZZZZZZ
EEEEEEEEEEEEEEEEEEEEEEE
FFFFFFFFFFFFFFFFFFFFFFF

Thanks,
Bash
