Clarification
Hi, I have a big file file with many blocks and i want to print only the maximum block which is block-200.So i need to find the starting point and end point of the block-200 and print as per the below output.To achieve this iam following the below way..i am not sure is this the best way...
step-1: iam finding the line numbers and blocknumbers and storing in a variable
Code:
1|200
9|199
14|200
20|200

step-2 finding the maximum block number which is
Code:
200

.
step-3 iam checking the block number with the above table and finding the start point and the end point
Iam getting 2 scenarios..one is startpoint and end point and the other is from startpoint till EOF.
step-4 Pass the startpoint and end point and print it.I got struck when iam trying to print the bock of data
Code:
INPUT FILE
-------------
block-200
print number of lines
sdfsdfsdfsdfsd
sdfsdfds
yrtyrtytr
tyrtyrt
rtyrtyrt

block-199
print number of lines
sdfsdfsdfsdfsd
sdfsdfds

block-200
print number of lines
sdfsdfsdfsdfsd
sdfsdfds
yrtyrtytr

block-200

chfsets

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

NAME

       chfsets - Changes limits for fileset quotas

SYNOPSIS

       /sbin/chfsets [-F limit] [-f limit] [-B limit] [-b limit] domain [fileset...]

OPTIONS

       Specifies  the  file  usage  soft limit (quota) of the fileset.	Specifies the file usage hard limit (quota) of the fileset.  Specifies the
       block usage soft limit (quota) in 1K blocks of the fileset.  Specifies the block usage hard limit (quota) in 1K blocks of the fileset.

OPERANDS

       Specifies the name of the file domain.  Specifies the name of one or more filesets.

DESCRIPTION

       The chfsets command enables you to change fileset quotas (file usage limits and block usage limits) of any AdvFS fileset.

       Filesets can have both soft and hard disk storage and file limits.  When a hard limit is reached, no more disk space  allocations  or  file
       creations  which  would	exceed	the limit are allowed.	The soft limit may be exceeded for a period of time (called the grace period). The
       grace periods for the soft limits are set with the edquota command.

       The command also displays the changes made to the file and block usage limits.

       Note that the root user can exceed fileset quotas.

       The chfsets command displays the following fileset information: Id

	      A unique number (in hexadecimal format) that identifies a file domain and fileset.  File H limit

	      The file usage hard limit of the specified fileset before the change followed by the new limit.  Block H limit

	      The block usage hard limit of the specified fileset before the change followed by the new limit.	File S limit

	      The file usage soft limit of the specified fileset before the change followed by the new limit.  Block S limit

	      The block usage soft limit of the specified fileset before the change followed by the new limit.

       Use the following commands to manipulate filesets: Displays the limits and actual number of blocks used by a fileset.  Displays space usage
       for the specified domain.  Displays the file and block usage limits for the filesets in a domain.  Changes the user or group block and file
       limits and grace period.  Turns on and off quota enforcement.

       For more information, see the reference pages for each command.

RESTRICTIONS

       At least one fileset within the domain must be mounted for the chfsets command to succeed.

       You must be the root user to run the chfsets command.

EXAMPLES

       The following example changes the file hard limit from 11 to 200 and block hard limit from 121 to 1000 for the  credit_fs  fileset  in  the
       account_dmn domain: # chfsets -b 1000 -f 200 account_dmn credit_fs

	     credit_fs
		    Id		  :  2c2f557f.000b15f4.3.8004
		    File H limit  :  11 --> 200
		    Block H limit :  121 --> 1000

EXIT STATUS

       The utility returns a 0 (zero) on success and a 1 (one) on failure.
