封装了一些常用操作的命令行工具

import { appendFileSync, readFileSync, writeFileSync } from 'fs-extra';

    const data = readFileSync(filePath).toString();
    let dataArray: string[] = [];
    const wordMode = mode === 'word';
    if (wordMode) {
        dataArray = data.split(' ');
    } else {

        const space = wordMode ? '' : ' ';
        if (dataArray[i].endsWith(space) && dataArray[i + 1] === space) {

            dataArray.splice(i + 1, 1);
