hi there, I want to understand what this code snippet is doing exactly. I have an idea, but I might be missing something. 

open F, "cat file | /usr/bin/mycommand";
my $def_slash = $/; $/ = ""; eval <F>; $/ = $def_slash;
close F;

Sorry that I can't post the command itself, maybe that's important in this case:(. My goal to catch any error returned from this command, but $@ does not catch anything after the eval :( Could you please advise? Thanks much
