EGADS. This worked beautifully!
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.
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.

Hope that makes sense.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,

autosupport
AUTOSUPPORT(8) Linux Programmer's Manual AUTOSUPPORT(8) NAME
autosupport -- interactive script to provide Digium[tm]'s support with information SYNOPSIS
autosupport [OPTION] [prefix] DESCRIPTION
autosupport is a script that is normally run by a user contacting Digium's Technical Support to automate gathering support information. It will probe the system for some run-time and system information, and generate a backup of Asterisk related configuration. An optional param- eter for a prefix may be specified which is typically used to specify a Digium Technical Support Ticket ID. The script requires root privileges to run, and writes all output in the home directory of the user running the script. For the purposes of this document, this will be referred to as /root/ henceforth. The system information is written to /root/digiuminfo.txt and the backup of configuration (and the system information file) are written to a tarball in /root/ with a base name of digium-info. A Date Stamp will be appended, and if specified the optional parameter will be a pre- fix. The tarball at least is expected to be attached to a support ticket with Digium. OPTIONS
Arguments: prefix Used to prefix the file names. Typically a Digium Technical Support Ticket ID Options: -n, --non-interactive Run without requiring user input -h, --help Show help about options FILES
