Maybe something like this?

#!/usr/bin/perl
@ls = `ls`;
chomp @ls;
foreach (@ls) {
        $before = $_;
        if(/\ $/) { chop $_; }
        s/\ /_/g;
        system("mv \"$before\" $_");
}

This is the kind of question which will come up with hundreds of
solutions from hundreds of persons. :-)

Before using above script you should make a backup first!

Best regards,
Paul
