I am guessing the back reference \\1 does not get passed to the toupper function inside the replacement part of gawk's gensub function:

Alternatively:

Code:

awk '{for(i=1;i<=NF;i++)$i=toupper(substr($i,1,1)) substr($i,2)}1'  infile

but that would squeeze spacing..

Or shortening the previous perl:

Code:

perl -pe 's/\b./\u$&/g' infile
