Re3: Can you delete a file by descriptor?

Thats pretty slick... I like it. You can get the same info from /dev/fd/n as well.

% perl -e'open($fh,"/tmp/file"); print readlink("/dev/fd/" . fileno($f
+h))'
/tmp/file

Nod. (BTW, this works because /dev/fd/ is a symlink to /proc/self/fd/, and /proc/self is (magicly) a symlink to /proc/(pid) for whatever process is following the link. We are using here a powerful strategy of synthesis: wishful thinking. -- The Wizard Book	[reply]
