@_the_cloud@mastodon.social that's a much prettier way of doing it than mine, and much more logical. Every time I use comm, I forget if it's 'comm -12' or 'comm -23' for the use case I want. Every time. It's also really sensitive to list order

@scruss@xoxo.zone Well, the options may be hard to remember, but the 'comm' utility was essential for performance. As it turns out, there's no need for 'grep' at all, because 'comm' has already preselected the matches! Now the script runs in approximately 1 second, orders of magnitude faster than before.
