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.

fs_whereis

FS_WHEREIS(1)						       AFS Command Reference						     FS_WHEREIS(1)

NAME

       fs_whereis - Reports each file server housing a file or directory

SYNOPSIS

       fs whereis [-path <dir/file path>+] [-help]

       fs whe [-p <dir/file path>+] [-h]

DESCRIPTION

       The fs whereis command returns the name of each file server machine that houses the volume containing each directory or file named by the
       -path argument.

OPTIONS

       -path <dir/file path>+
	   Names each AFS file or directory for which to return the host file server machine. Partial pathnames are interpreted relative to the
	   current working directory, which is also the default value if this argument is omitted.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output includes a line for each specified directory or file. It names the file server machine on which the volume that houses the
       specified directory or file resides. A list of multiple machines indicates that the directory or file is in a replicated volume.

       Machine names usually have a suffix indicating their cell membership. If the cell is not clear, use the fs whichcell command to display the
       cell in which the directory or file resides. To display the cell membership of the local machine, use the fs wscell command.

EXAMPLES

       The following example indicates that volume housing the directory /afs/abc.com resides is replicated on both "fs1.abc.com" and
       "fs3.abc.com":

	  % fs whereis -path /afs/abc.com
	  File /afs/abc.com is on hosts fs1.abc.com fs3.abc.com
