Split a file into multiple files based on the input pattern
I have a file with lines something like.
Code:
......
123_start
......
.......
123_end
....
.....
456_start
......
.....
456_end
....
.....
789_start
....
....
789_end

if i give the input as $a = _start and $b = _end, it should split the contents and save as different files like,
Code:
123_start
..
...
123_end

as one file with filename as 123. from the above example it should give 3 different files as 123, 456, 789.

Please let me know the solution.

For now i am executing everytime to get a file individually as given below. i need a replacement to simplify my task.
Code:
a=12345_start
b=12345_end
awk '/'"$a"'/,/'"$b"'/' in > out

ocamlwc

OCAMLWC(1)						      General Commands Manual							OCAMLWC(1)

NAME

       ocamlwc - count the lines of code and comments in OCaml sources

SYNOPSIS

       ocamlwc [options] [files]

DESCRIPTION

       ocamlwc	is  a program to count the number of lines of code and documentation in OCaml sources.	It assumes its input to be lexically well-
       formed.	If no files are given, then ocamlwc reads from stdin.

       The first column of the output lists the number of source lines of code, the second column the number of lines of  documentation,  and  the
       third the respective filename.  If ocamlwc acts on more than one file, then it prints a total in the last line.

OPTIONS

       -p     Print percentage of documentation (in an additional column after the filename).

       -c     Print only the code size, i.e., omit the documentation column.

       -e     (everything) Do not skip headers.  A header is the first comment in a file.

       -a     (all)  Do  not  skip generated files.  foo.ml is a generated file if one of foo.mll, foo.mly, or foo.ml4 is amongst the given files.
	      foo.mli is a generated file if foo.mly is amongst the given files.

       -h     Print short usage information.
