How to assign bit shift to a variable? 1

whn · Jul 12, 2016

I know this line works:

Code:

print "OK!! Child($$, $pid) $res ended with ", $? >> 8; print "\n";

But how do I assign the line above into a variable? e.g.

Code:

$logMsg .= "OK!! Child($$, $pid) $res ended with ", $? >> 8;
$logMsg .= "\n";

While compiling it, I got this:

Code:

Useless use of right bitshift (>>) in void context at...

How to make it work? Thanks for the help.
