BEGIN END questions
Why would you need to use this in a script?
Why can't you just use print to print out what you want printed in the begining and print for what you want at the end.

So this:

Code:
nawk 'BEGIN {print "this is the first line"}
{print $1 $2 $3}
{print $5 $6}
END {print "this is the last line"}'

why can't i just or why would I not use:

Code:
print "this is the first line"
nawk 
'{print $1 $2 $3}
{print $5 $6}'
print "this is the last line"

end

END(7)							  PostgreSQL 9.2.7 Documentation						    END(7)

NAME

       END - commit the current transaction

SYNOPSIS

       END [ WORK | TRANSACTION ]

DESCRIPTION

       END commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a
       crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT(7).

PARAMETERS

       WORK, TRANSACTION
	   Optional key words. They have no effect.

NOTES

       Use ROLLBACK(7) to abort a transaction.

       Issuing END when not inside a transaction does no harm, but it will provoke a warning message.

EXAMPLES

       To commit the current transaction and make all changes permanent:

	   END;

COMPATIBILITY

       END is a PostgreSQL extension that provides functionality equivalent to COMMIT(7), which is specified in the SQL standard.

SEE ALSO

       BEGIN(7), COMMIT(7), ROLLBACK(7)
