I dont know how to extract the lines from a file using perl commands?

for example if there are hundred lines in a file.if the first pattern which is to be matched is in one line another pattern is in another line .how i have to extract those lines present in the file using PERL COMMANDS.


example program:


0000000 nul ack nul stx nul etx nul fs soh stx nulj nul stx


0000020 nul stx nul so nul ack nul j nul stx nul can nul s


0000040 nul ack nul dc2 stx ack o u t p u t File


0000060 . g d s nul dc4 etx enq %26gt; A ht F '


0000100 9 D 8 / sp esc Z T nul fs enq stx nul


0000120 nul can nul stx nul so nul ack nul j nul stx nul


0000140 nul so nul ack nul dle ack ack t ox c o n t _


0000160 C O N T nul eot bs nul nul ack cr stx nul


0000200 so stx nul y nul , dle etx nul nul nul nul nul


0000220 nul nul vt 8 nul nul nul nul nul nul vt 8 nul 0


i want to extract the lines in the line number 0000140 from ack ack to line number 0000160 (nul eot) .similarly thuout the file

The easiest way to do this is to count back from the end of the array.





For instance, if an array has three values,


$item[0], $item[1] and $item[2] then you can access the last with:


$item[-1]... an easy way to reach it!
