therefore masking’xxox- x’will produce’xxaxbeex’ for’deadbeef’
The same mask as’deadabbabeef”xxox-x’ will produce’xxaxabbabeex’
How can I use the s operation concisely Where is the symbol?
$mask =~ s/-/'o' x (length $str- length $mask)/e;
$str =~ s/(.)/substr($mask, pos $str, 1) eq'o'? $1:'x'/eg;

I have a string like’xxox-x’, and I want to block every line in the file as follows:
> x is Ignore (or just set it to a known value)
> o stay the same
> – is a variable length field that can keep everything else unchanged
therefore masking’xxox-x ‘For’deadbeef’ will produce’xxaxbeex’
The same mask as’deadabbabeef”xxox-x’ will produce’xxaxabbabeex’
