Do you need anything more sofisticated than "s/0//"?


$ perl -e '$a=10; $a =~ s/0//;print $a, "\n"'

If it's just a single character I'd use 'tr/0//d'.

I'm not entirely sure what is meant by "empty string". It might
possibly mean replacing '0' with a space: 'tr/0/ /'.

The OP has under-specified his problem. What he wants may also be the
common idiom "$x ||= ''". It replaces 0 (and undef) with an empty string.
