2020-05-18 entr, a wrapper around inotify

Shortly after my post from last year describing how I use inotifywait to start programs on file change, one of the readers emailed me about an utility called entr. It is an extremely simple-to-use tool which just gets the filelist to watch on stdin and a command to execute when any of the files changes as CLI arguments – and that’s pretty much it. (That does not imply it is simplistic – according to its website, it performs some non-trivial stuff under the hood.) Thanks!
