Question

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 ...

Answer 1

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
