테스트를 진행하다보면 10초, 20초 단위로 옵션을 변경하여 결과를 볼 때가 많다. 이 때 time이나 쉘 스크립트를 이용해서 측정할 수 있겠지만 두 개 이상의 명령어를 수행할 때에는 비교의 어려움이 있다. 그럴 때에는 현재 시간에 기반하여 흐름을 파악하는 것이 편한데 그 때 사용하는 패키지를 소개한다.

Prepending a timestamp to each line of output from a command
I wish to prepend a timestamp to each line of output from a command. For example: foo bar baz would become [2011-12-13 12:20:38] foo [2011-12-13 12:21:32] bar [2011-12-13 12:22:20] baz ...where...
