Get items unique only to list1

…from two lists with some overlap. Spent some time working in Python on this problem. Afterwards, I realized it’s a shell one-liner.

comm -23 <(sort f_most) <(sort f_some) | sort -n > f_uniq_to_1

I re-sort the output numerically since comm assumes its input is sorted lexicographically, and I happen to be comparing lists of numbers.
