Scripting the process to edit a large file
Hi,

I need to make a script to edit a file. File is a large file in below format

Version: 2008120101
;$INCLUDE ./abc/xyz/Delhi
;$INCLUDE ./abc/xyz/London
$INCLUDE ./abc/xyz/New York

First line in the file is version number which is in year,month,date and serial number format. Each time when file is changed current month,date and serial number is changed.

Other 3 lines with INCLUDE statements are point of focus, where only one line will be active at a time without comment. I need to have a script which can change the version number each time when any change is being made and if input parameter is London then line with reference to London should be uncommented and other two should be commented. Same way if input parameter is New York then line with new york should be uncommented and other two should be commented and version number should change. I hope I could clarify the situation and my requirement. I am not a core Unix guy, so thought to take genious people's help. Thanks a lot in advance.

Regards.

readproctitle

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

NAME

       readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).

       readproctitle is available in daemontools 0.75 and above.

SYNOPSIS

       readproctitle L D

DESCRIPTION

       L consists of any number of arguments.  D is one argument consisting of at least five dots.

       readproctitle  reads  data  into  the  end  of  D,  shifting D to the left to make room. This means that the most recent data is visible to
       process-listing tools such as ps(1).  readproctitle always leaves three dots at the left of D.

       For example, if

	readproctitle io errors: ....................

       reads the data

	fatal error xyz
	warning abc

       then its command-line arguments change to

	readproctitle io errors: ... xyz!warning abc!

       with a newline character in place of each !. Process-listing tools typically show the newline character as ? or 
.

       readproctitle exits when it reaches the end of input.

       Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle  L	D.
       I have not seen a system with a limit below 512 bytes.
