shell脚本批量添加用户的脚本

在 上张贴 由 脑袋发表回复

好不容易放假了，重新写个批量添加用户的脚本。
思路有些混沌了，还望大家多多指教。

这个脚本还有很多地方需要改进，比如算法，比如数据的处理。
希望大家不吝提出修改意见。

  2. # Name: useraddmuti
  3. # Descripton: To add users to your system. Users can be list in a file.
  4. #             To exec this command your ID must be 0.
  5. # Author: [email protected]
  6. #———————————–
