very nice, but you broke it :-) input: this go thises kablooey output: this goes kablooey this works: #!perl -p0 s/^((\S+ ).+)\n\2/$1 /m&&redo here's another (equal length, stupid \Q :-) this works since perl kindly resets the //g search upon modify. #!perl -p0 s/\G\n\Q$1/ /while/(\S+ ).*/g and if we ever get those variable length lookbehinds in perl: #!perl -p0 s/(?<=^\1.+)\n(\S+ )/ /gm or something thereabouts :-) -bass
