It is possible if the remote file is on something like a nfs filesystem or a smb share. Out of the box, open() is restricted to the local filesystem. You could overload open() to use LWP, download to a temporary location and open the file there. If you do that, I think `use URI; sub URI::open { use LWP; # fetch to /tmp and open # beware error conditions, # net adds a lot of new ones }` [download] would be a reasonable start. You might want to write a module subclassing URI instead. In my own code, I'd reserve open() for local operations. After Compline, Zaxo	[reply] [d/l]

If you install LWP, you get a very nice program called `GET`. This program gets the contents of a URL and prints it out. You can read from this output like a file by using a pipe in the `open()` command. `use strict; open(FILE, 'GET http://www.yahoo.com/index.html \|'); while(<FILE>) { print $_; } close FILE;` [download] If you don't want to use LWP there are other programs that can get the contents of a URL. These programs can be used the same way. It should work perfectly the first time! - toma	[reply] [d/l] [select]

Probably the easiest way to do it is copy the file to the local system with scp or rcp or Net::FTP or somehing like that, edit it, and then push it back up... all of with can be done within perl... you could overload or simply create an open routine which did that for you, and wrote it back on close... - Ant - Some of my best work - Fish Dinner	[reply]
