sum does something totally different than I expected. With [1]
comes the more reasonable
$ git grep -c -F -e '`' -- 't/*.sh' | cut -d: -f2 | addup
485
$ git grep -c -F -e '$(' -- 't/*.sh' | cut -d: -f2 | addup
2620
$ git grep -c -F -e '`' -- '*.sh' | cut -d: -f2 | addup
594
$ git grep -c -F -e '$(' -- '*.sh' | cut -d: -f2 | addup
3133
So the code bloat and use of backticks are less dire than I feared.
[1]
addup () {
sum=0
while read term
do
: $((sum = $sum + $term))
done
echo $sum
}
