close and autodie on pipesby apomatix (Novice)
|on Jun 29, 2012 at 18:06 UTC||Need Help??|
apomatix has asked for the

Now let's try to use autodie:
No good, that breaks it:
It is the "close" statement. So we can take that out.
Now it is broken differently---it has lost the exit status:
I need to call close in order to get the exit status of a pipe.
So now I have settled on this ugly thing:
That seems to work, but I'm not doing any error checking on the close statement:
Can I use close with autodie when my pipe fails? If not, how should I check for errors?
