This is probably simple, but I'm not getting anywhere. What I'm actually trying to do in my script is more complex, but I've simplified my code into the following to isolate the issue. Take a look at this simple script: 
#!/usr/bin/perl
$res = `echo test`;
print $res;
print $! . "\n";'

The output to the shell is as follows: 
test
Bad file descriptor

So, what I don't understand is why $! is "Bad file descriptor"? I can choose not to check $! and my script runs fine... but I'm obsessing over why it would present an error at all.

Also, I'm not using system() because I need the data from STDOUT. Any help is appreciated! Thanks!
