I need to check the name to conform to the following conventions: valid names are comprised of only alphanumeric characters(a-z A-Z and 0-9) plus the characters '-', '_', and '.'. Names must begin with a letter.

someone told me to use this

$name =~ /\A[a-zA-Z][\w.-]*\z/;

[download]

but it treat "s@--__" and "s!!!@@@___" to valid which should be invalide name, casue \w in perl include @ and ! and punction sign, Any hints on this?

Thanks,
