search and replace in text file?

[Anon]

Looking for some help to do the following

I have a text file that is setup like this

filename1, filedesc2, modified date
filename2, filedesc2, modified date

and so on.

i want the user to be able to rename the filename, and then have the text file be updated with the new name. So say the rename filename1 to filetest1. I need the file in the dir to be updated with the new filename (basically already have the code written for that), but then I need the text file i have listing the files to get rid of filename1 and then rename it to filetest1. Any help would be appreciated.

yeah, i can rename the actual file , no problem. I already have the code for that. But I'm also keeping a text file of the files in the directory, plus their file descriptions and date modified. So I want this text file to be updated with the new file name (getting rid of the old filename) and that is my problem...

this would be very easy if i was using MySQL, I relize that...but due to size limitations, I have to use the text file instead.
