|this 'data' is a regular expression
No, it is not a regular expression, only the duck
is a regular expression. s
is a Perl operator. If you can it would be a lot easier to have two columns, the first being the RE pattern ('duck') and the second being the replacement text ('luck') and then read them into variables (using split
) - it is perfectly valid (and common) to store an RE in a Perl variable.
Otherwise you will be reduced to doing nasty things like eval
, and you don't want to go there.
