The script I'm working on is supposed to read a file, which contents is dynamically changed (/proc/stat). I need to re-read the first line about every second. That makes me wonder:

- How do I move the access pointer to the beginning of the file (and can I do it at all in a text mode)?

- Do I need to close and reopen the file every time I want to read the updated content?

Any pointers are appreciated...
