Well, -n doesn't print, but -p does print :)

$ perl -le " print qq{a;b;c;d} " a;b;c;d $ perl -le " print qq{a;b;c;d} " | perl -ne " tr/;/\n/ ; " $ perl -le " print qq{a;b;c;d} " | perl -pe " tr/;/\n/ ; " a b c d

    ok, thanks for the quick reply. It seems I was assuming -i edits 'in place'. And -n / -p only controlled if STDOUT was printed to or not.(i think it was SED).

    Just trying to analyse more complex stuff while tripping over the 'simple' stuff...

        Yes, maybe one for the chatterbox on reflection.

        I'm reading a lot about a lot, packages,modules,symbols, today. Then this invocation frustration arose. Couldn't see the wood for the trees.

        These one liners do seem to have a way of over extending themselves.
