So what you what to match is a followed by zero or more not a's and then the end of the string.
<[a]> is the perl6 regex for a range comprising of a alone you can negate that like so <-[a]> Giving us perl6 -e 'my $x="abcabcabc"; $x ~~ s/a <-[a]>* $/xyz/; say $x;' (There's probably a better way, this was just my first attempt) On Tue, 1 May 2018 at 14:37 ToddAndMargo <toddandma...@zoho.com> wrote: > Hi All, > > I am trying to change the last three letters of a string > > $ perl6 -e 'my $x="abcabcabc"; $x ~~ s/"a.*"$/xyz/; say $x;' > abcabcabc > > I want abcabcxyz > > And, in real life, only the "a" will be a know letter. > Everything else will vary.
