Re: Re: should this backspace removal code be done better?

tr/\b//d would probably be the most efficient form but s/\010//g will also do the job. What is with all the .\010 and while(1)'s in the replies?

$_ = "hello\b\b\b\b\b\b\hello\b\b";
tr/\b//d;
print length($_), $/, $_, $/;
__DATA__

You miss the point or I do. When you remove the \b, you also have to remove the character behind it over which it backspaced. In your example, the final output should be something like "hel".
