No. Please remember that the mini-filesystem belongs to the node and the current working directory belongs to the user running the node. > While it is in cache...we will move it to permanent Yes. > - supose in cache it is 2.data shud i move it as 2.data > or abcd.jpg to permanent... Well, moving from "2.data" to "2.data" is a no-op. You just need to change a bit somewhere in your mini-filesystem to indicate that the file is in permanent space now. > my guess is only in current working > directory we will change name and in permanent and cache it > always remains as (fileno).data. i just wanted to ask if it was > correct? I don't really think of it as "changing name". It's saving the file as a specified filename. Just like when you download a file from the internet, the browser often asks you to give the file a name as soon as the file leaves the browser space and into your local directory. -- Bill Cheng // bill.cheng@usc.edu
