The >> operator is the Append operator. I want to Read the Files contents. Depending on those contents (if contents = 0) then Truncate and write "1". I do not want to close the file and reopen it with a different operator as that will allow for the file to be opened by another process. There needs to be a way to open a file Read/Write, to Read the Data and then when writing to the file Truncate the data and write a value out.
