[question] Searching through a file to find and change on line

Hello,

I am trying to store data in a file in the format

name:password:integer

is it possible to write a function that searches through that file, finds that specific line, and can either copy it or change the line?

or is it easier to

myTable = {}
myTable[1] = textutils.serialize({name,password,integer})
myTable[2] = textutils.serialize({name,password,integer})
myTable[3] = textutils.serialize({name,password,integer})

et cetera, and search thru the table and look for the needed line, deserialize it and return a result?

Thanks,
~Matt

There are already function to do that in the Lua String API. They use Regular Expression, it is a bit tricky if you are not familiar with them, but you should check this out.

You could list the lines of a file then edit the single lines using string.sub
Something like that.
