Execute Commands When File Changes with entr

Most people know about entr but I didn’t know that to get multiple lines of shell scripting to work you need bash (or some shell). This is because entr makes a syscall to exec which requires a single executable.

entr bash -c 'clear; go run main.go' <<< main.go

Or

entr bash -c "clear; go test ./..." < <(ls -1 **/*.go)
