cut -f1 -d'-' inputfile | sort | uniq -c
cut -f1 -d'-' will treat the file as dash-delimited and return only the first column in each line.
sort is necessary for uniq to work properly.
uniq -c shows only unique lines from the sorted input, including a count.
awk -F- 'NF>1 {count[$1]++}
END {for (i in count) print i, count[i]}'
