标题: yum for cygwin
本帖最后由 damcool 于 2014-04-03 19:26 编辑

前些日子在用apt-cyg/cyg-apt来更新自己的cygwin安装包，太TMD让人心焦了。于是自己写了一个"yum for cygwin"，功能还行吧，我需要的都有了。分享一下。

  52.                       data.
  53.   
  54.   info [pkgs..]       Display the briefing information of the given package(s)
  55.   info installed      Display the briefing information of installed package(s)
  56.   info updates        Display the briefing information of updating package(s)

  58.   install [pkgs..]    Install the given package(s) with required package(s)
  59.
