We can help you much better if we can actually see what you're doing, so please include sample code. A working pattern for modifying a file goes like this: 1. open old file or reading 2. open temporary file for writing 3. read a line from the old file 4. if the line matches your criteria, then modify the line 5. write the line to the temporary file 6. If you have not reached the end of the old file yet, continue at 3. 7. close the old file 8. close the temporary file 9. rename the old file to a temporary filename 10. rename the temporary file to the name of the old file 11. optionally, delete the old file It's not an in-place edit, but it works. If you need to do in-place edits, you should look at seek() and understand the constraints of doing an in-place edit.
