in reply to How to remove underscore before every dot using perl?

Hello finddata,

For the transliteration operator, the /c modifier complements the searchlist, and the /d modifier causes found-but-not-replaced characters to be deleted. So the expression tr/a-zA-Z//dc says: Delete any character that is not a letter. But that includes the dot. So you need to add in a dot, to say: Delete all characters except letters and dots:

$str =~ tr/a-zA-Z.//dc;

But in this case I think it would be clearer to use an explicit substitution:

$str =~ s/_\././;

Hope that helps,
