Hi,
What does * mean here?
also rc|=0, how to interpret it?
thanks!
The * gives access to the typeglob. See `perldoc perldata` and search for /typeglob/. In this case, it is aliasing the `our` variable $r with the special variable $0.
#!/usr/bin/perl
use strict;
use warnings;
our $r;
*r = 0;
print "This script name is $r\n";
$rc |= 0; means to bit-wise OR the variable $rc with 0 (zero). This is equivalent to: $rc = $rc | 0;
See `perldoc perlop` and search for /Assignment Operators/.

I love Perl; it's the only language where you can bless your thingy.
Perl documentation is available at perldoc.perl.org. The list of standard modules and pragmatics is available in perlmodlib.
