One minor question while I try to work out all the syntax: the two sets of files for comparison (what I previously referred to as 001.txt and blah1.txt) actually have the same numbering system - since there are hundreds of them - but with a different letter prefix for each set, i.e., a001..a300.txt and b001..b300.txt. I only want the numbers starting with a to increase without changing b. Where should I specify/add this prefix?

Sorry for the confusion!

Just tried it. Smilie The search and replace bit works perfectly. It only creates a single new file though, called file02. However, it's a little strange because if I delete this file and run the script again, the replacement is called file03 (instead of file02 again). Hope that makes sense.
Hello pseudo.seppuku,

That's because you haven't run it as a script and when you ran it as a command, variable named i's value will be there in memory of shell and it will take it from there. When you save this as a script and run this will not happen. As for file names I am still little confuse as you need to show like current_file_name--> new_file_name etc, I hope this helps you.

Thanks,
R. Singh

tomoyo-patternize

TOMOYO-PATTERNIZE(8)					  System Administration Utilities				      TOMOYO-PATTERNIZE(8)

NAME

       tomoyo-patternize - utility to convert pathnames in policy into patterns

SYNOPSIS

       tomoyo-patternize

       tomoyo-patternize [configfile]

DESCRIPTION

       This program reads domain policy from standard input and replaces pathnames with patterns. Replacement rules are defined in
       /etc/tomoyo/tools/patternize.conf. The resulting policy is sent to standard output and is useful to shorten and simplify domain or
       exception policy.

       Pathnames used for domain names themselves will not be replaced. Only the first matching rule is used for any particular pathname. If a
       pathname does not match any rules, it is left unchanged.

EXAMPLES

       Replace "proc:/self/fd/0" with "proc:/self/fd/$"
	     rewrite path_pattern proc:/self/fd/$

       Replace "proc:/123/status" with "proc/$/status"
	     rewrite head_pattern proc:/$

       Replace "dev(8,1):/etc/mtab~456" with "dev(8,1):/etc/mtab~$"
	     rewrite tail_pattern /etc/mtab~$

       Replace "/tmp/phpZjk1k3" with @GROUP1
	     rewrite path_pattern /tmp/php?????? @GROUP1

       Replace integers between 0-100 or 100-200 with @GROUP2
	     rewrite number_pattern 0-100 @GROUP2
	     rewrite number_pattern 100-200 @GROUP2

       Replace loopback addresses with @LOCALHOST
	     rewrite address_pattern 127.0.0.1 @LOCALHOST
	     rewrite address_pattern 0:0:0:0:0:0:0:1 @LOCALHOST

       See the configuration file for more information on rule syntax.
