This is a kind of hacky way to exit with status code 1 if goimports -l . lists files that are not imported correctly.
Explanation:goimports -l . lists all files that aren't formatted correctly, without modifying those files. This output is piped to read which fails if there is no input - e.g. if there are no invalid files listed by goimports. But since the job should file if readdoesn't fail, this expression is negated with !.
If the job fails, i.e. the exit code is 1, the affected files that have to be formatted properly should be listed. The easiest way to do this should be to store the output of goimports -l . or just run it again if the read expression doesn't fail.
The CI job for checking the Go imports currently runs
! goimports -l . | read.https://github.com/dominikbraun/timetrace/blob/b4b7c153e92cd869ac34e92fedc0d6a16460862c/.circleci/config.yml#L25-L27
