How to print lines from a files with specific start and end patterns and pick only the last lines?
Hi, I need to print lines which are matching with start pattern "SELECT" and END PATTERN ";" and only select the last "select" statement including the ";" .
I have attached sample input file and the desired input should be as:

INPUT FORMAT:

Code:
SELECT  
ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1
limit 1;

delete from test2;

SELECT  ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1
limit 1;
create table as SELECT  
ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1
limit 1;

SELECT  ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1
limit 1;


SELECT 
ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1
limit 1;

SELECT  
ABCD,
DEFGH,
from test1
limit 1;

delete from test2;

create table as SELECT  
ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test1345
limit 1;

create table as SELECT  ABCD,
DEFGH,
DFGHJ,
JKLMN,
AXCVB,
DFVBNM,
QWER,
RTU,
TYUI,
IOPL from test123
limit 1;



OUTPUT FORMAT

Code:

wdmd

WDMD(8) 						      System Manager's Manual							   WDMD(8)

NAME

       wdmd - watchdog multiplexing daemon

SYNOPSIS

       wdmd [OPTIONS]

DESCRIPTION

       This  daemon opens /dev/watchdog and allows multiple independent sources to detmermine whether each KEEPALIVE is done.  Every test interval
       (10 seconds), the daemon tests each source.  If any test fails, the KEEPALIVE is not done.  In a standard configuration, the watchdog timer
       will  reset the system if no KEEPALIVE is done for 60 seconds ("fire timeout").	This means that if single test fails 5-6 times in row, the
       watchdog will fire and reset the system.  With multiple test sources, fewer separate failures back to back can also cause a reset, e.g.

       T seconds, P pass, F fail
       T00: test1 P, test2 P, test3 P: KEEPALIVE done
       T10: test1 F, test2 F, test3 P: KEEPALIVE skipped
       T20: test1 F, test2 P, test3 P: KEEPALIVE skipped
       T30: test1 P, test2 F, test3 P: KEEPALIVE skipped
       T40: test1 P, test2 P, test3 F: KEEPALIVE skipped
       T50: test1 F, test2 F, test3 P: KEEPALIVE skipped
       T60: test1 P, test2 F, test3 P: KEEPALIVE skipped
       T60: watchdog fires, system resets

       (Depending on timings, the system may be reset sometime shortly before T60, and the tests at T60 would not be run.)

       A crucial aspect to the design and function of wdmd is that if any single source does not pass tests for the fire timeout, the watchdog	is
       guaranteed  to fire, regardless of whether other sources on the system have passed or failed.  A spurious reset due to the combined effects
       of multiple failing tests as shown above, is an accepted side effect.

       wdmd will exit if a watchdog driver is not loaded.

       wdmd cannot be used on the system with any other program that needs to open /dev/watchdog, e.g. watchdog(8).

   Test Source: clients
       Using libwdmd, programs connect to wdmd via a unix socket, and send regular messages to wdmd to update an expiry time for their connection.
       Every test interval, wdmd will check if the expiry time for a connection has been reached.  If so, the test for that client fails.

       (Other test sources such as scripts executed each test interval may be added in the future.)

OPTIONS

       -D     Enable debugging to stderr and don't fork.

       -H num Enable (1) or disable (0) high priority features such as realtime scheduling priority and mlockall.
	      Default 1.
