Mass find & replace

Hi. I'm just starting with C, I've done quite a bit of programming in some other languages. I find it easy for myself to learn by example, and what better example than a utility I need?

Basically, I have thousands of files inside hundreds of folders. I want a program to go through those files, and inside each, there may be multiple instances of things like:

Code:

example asdf
attribute1 sdff
attribute2 12
attribute3 test
end

I need it to search through each of those instances, and find a specified attribute, and change the value. However, there are also rules for other attributes. Example:

Whenever attribute 2 is equal to 12, make attribute 3 equal "test2".

Thanks.

So what do you want an example of string searching or directory searching? Also what have you attempted thus far?

Sounds like a job for Perl

Otherwise, not too hard in C but a bit cumbersome. I would suggest getting the parsing of the files down pat (i.e. for one file at a time), then look at the FAQ which gives examples of a "directory walker".

Thanks, but I've just realized that, since I'm a bit low on time, I should probably just stick with a language I'm familiar with. Perhaps I'll try C (and perl) some other time.
