Javascript 复制带时间戳的文件，重命名它并动态更改内容

我有大约30个迁移文件（sequelize），看起来像下面这样，我想复制到另一个表的迁移中，同时更改迁移文件的名称（sequelize依赖于utc时间戳）并更改文件中的表名：

"use strict";

module.exports = {
  up: (queryInterface, Sequelize) => {
    return queryInterface.addColumn("Providers", "column-name", { type: Sequelize.DECIMAL(8, 2) });
  },

  down: (queryInterface, Sequelize) => {
    return queryInterface.removeColumn("Providers", "column-name");
  }
};

^^那剧本似乎成功了

for f in migrations/*[ce]c-to*; do cat "$f" | sed 's/Providers/PracticeAssignments/g' > migrations/$(date +'%Y%m%d%H%M%S' -u)-$(echo $f | sed 's/provider/practice-assignment/g' | cut -d'-' -f2-); done
