연휴 기간동안 gee라는 도구를 만들었습니다. tee랑 비슷한 도구이고 추가적인 기능들이 포함된 tee라고 생각하시면 됩니다. 오늘은 간단하게 gee에 대해 소개할까 합니다.

It is the current holiday season in South Korea. I had some time during that period, so I made and released simple tools focusing on the functions I needed. It’s gee.

Gee is tool of stdin to each files and stdout. It is similar to the tee command, but there are more functions for convenience. In addition, it was written as go
