A nifty trick when your one-liners get out of hand is to use B::Deparse on it:

perl -MO=Deparse -lne 'print if s/0010 0010.*\/\/.*\/\///'

which gives you an approximation of what Perl runs:

LINE: while (defined($_ = <ARGV>)) {
    chomp $_;
    print $_ if s[0010 0010.*//.*//][];
}

This is some ugly code, so I'd rewrite that to be more sightly:

#!/usr/perl -w
use strict;

while (defined(my $line = <ARGV>)) {
    chomp $line;
    print $line if s[0010 0010.*//.*//][];
}

or, if you're interested in post-processing the lines in your script:

#!/usr/perl -w
use strict;

my @interesting_lines = map  { s[0010 0010.*//.*//][] ? $_ : ()} 
                        (<ARGV>);
print "Name: $_"
  for @interesting_lines;

Update: Corrected last snippet to work like the previous snippets
