如何在一行中执行多个命令 [英] How to execute multiple commands in a single line

问题描述

我知道Unix有以下命令可以在一行执行多个命令，我该如何在DOS？

  command1; command2; command3 ... 
  

解决方案

Googling给了我： p>

---

命令B 执行命令A ，然后执行命令B （没有任何评估）

---

命令B

执行命令A ，并将其所有输出重定向到 >命令B

---

命令A&命令B 执行命令A ，在运行后评估错误级别，如果退出代码errorlevel）为0，则只能执行命令B

---

命令A ||命令B

执行命令A ，评估此命令的退出代码，但为0，则只能执行命令B

---

I know Unix has the following command which can execute multiple commands in a single line, how can I do this in DOS?

command1 ; command2 ; command3 ...

解决方案

Googling gives me this:

---

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

---

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

---

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

---

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B
