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?
In other words, the actual lines look more like this:
As you can see, the current script would change the numbers for a (as intended) but also the corresponding number for b. This wouldn't be difficult to cross-check if I only had a few lines, but with hundreds, it becomes somewhat more tedious to correct manually. Sorry for the confusion! I was trying to keep my first post as simple as possible.

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.

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.
Sorry, the first comment (regarding prefixes) was referring to RudiC's script.
I only just started fiddling with Linux recently so that's good to know.
However, what I meant about your script was that it only creates a single new file (file001 with string 001 -> file002 with string 002). I need this done a few hundred times, until file300 with string 300.

Not sure I get it - do you want the "a" numbers modified in the the file, or work on the file names starting with "a" only? I case of the former, try gsub (/a001/, "a" TCNT, T), in case of the latter, try a*.txt for the file name parameter.
