復制帶時間戳的文件、重命名並即時更改內容

Question

我有大約 30 個遷移文件（續集），如下所示，我想將它們復制到另一個表的遷移中，同時更改遷移文件的名稱（續集依賴於 utc-timestamp）並同時更改文件中的表名時間：

"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");
  }
};

Answer 1

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

^^那個腳本似乎成功了！
