Re^2: Perl file handles

I appreciate the response, and I guess I did not catch the mention of using close(DATA). All CB showed me was "All is quiet".

That being said, the above code and it doesn't work.

I use :

system qq{$Command "$0" >nul 2>&1};

close(DATA);

Same as usual. File cannot be deleted or renamed.

Wrong order. Closing DATA after the child has finished running will have little effect on the child.	[reply]

Ah! that did work. So, the idea is to close the DATA handle BEFORE you spawn the child, so the handle is not passed to it in the first place? I was thinking you closed the handle between the child being spawned and the parent process closing. But then I assume the child would still have a pointer back to the originating file? I am still unclear about how threading in perl works.	[reply]

No, the idea is to close the DATA handle BEFORE you spawn the child in order to release the lock BEFORE the child tries to delete the file. I am still unclear about how threading in perl works. I don't see how this is relevant to this conversation.	[reply]
