Question

我有一个要在群集中运行的bash脚本。但是我遇到了以下错误：

history.push

我想做的是读取目录中的所有文件。然后根据该文件是否带有单词“ hard”，“ soft”或“ neutral”，我要在集群上运行特定命令。

import React, { useState /* , useEffect */ } from 'react'
import useForm from 'react-hook-form'
import Logo from '../assets/images/logo-icon-orange.png'
import TextInput from '../components/TextInput'
import Footer from '../components/Footer'
import AnimatedButton from '../components/AnimatedButton'
import logger from '../logger'
import { sleep } from '../utils/promise'
import PasswordResetSchema from './validation/PasswordResetSchema'

const PasswordResetPage = ({ history }) => {
  const [isSubmitting, setSubmitting] = useState(false)
  // const [isDone, setDone] = useState(false)
  const { register, handleSubmit, errors } = useForm({
    validationSchema: PasswordResetSchema,
  })

  const onSubmit = async data => {
    setSubmitting(true)
    await sleep(2000)
    logger.info('form data', data)
    // setDone(true)
    history.push('/confirmation')
  }

  // useEffect(() => {
  //   if (isDone) {
  //     history.push('/confirmation')
  //   }
  // })


  return (
    <form onSubmit={handleSubmit(onSubmit)} noValidate>
      <div className="text-center mb-4">
        <img className="mb-4" src={Logo} alt="Striver" width={72} />
        <h1 className="h3 mb-3 font-weight-normal">Password reset</h1>
        <p>Enter your email address below and we will send you instructions on how you can reset your password.</p>
      </div>

      <div className="form-label-group">
        <TextInput type="email" id="email" register={register} label="Email address" errors={errors} />
      </div>

      <AnimatedButton actionTitle="Next" isSubmitting={isSubmitting} />
      <Footer />
    </form>
  )
}

export default PasswordResetPage

完成

此代码应生成文件，但出现上述错误。有人可以解释为什么我收到此错误吗？

Answer 1

在bash中，变量赋值在名称和值之间不允许有空格。 i_hard = 0解释为命令i_hard，用两个参数调用：=和0。请改用以下内容：

i_hard=0

Answer 2

据我所知，赋值运算符周围不应有空格，如下所示：

variable=6

在bash中初始化变量
