Was just working on the schedule for the Beginner Boost and needed to
know how many weeks I was actually planning by totalling up all the
lines with (n week(s)) in them. Just the sort of job for Vim and
UNIX filters!
#!/bin/bash
weeks=0
while IFS= read -r line; do
echo "$line"
if [[ $line =~ \(([0-9]+)\ weeks?\) ]]; then
((weeks+=${BASH_REMATCH[1]}))
fi
done
echo
echo "TOTAL: $weeks"
