Yup, upgrades until 2016 likely overwrote earlier links to 2015, 2014,..

The awk thing just reduces the above to the 9th field (i.e. "a2ping"), so you could in principle save the list to a file, say remove.me, and then

for i in `cat remove.me` ; do rm /usr/local/bin/$i ; done

(with a sudo somewhere, and do check carefully...)

Yep. That should solve things, provided there's an a2ping in /Library/TeX/texbin
